What is the difference between silicone and plastic? From the perspective of the material itself, performance characteristics, and where it can be used: silicone is an elastic polymer material with silicon oxygen bonds, belonging to the rubber category; Plastic is a plastic material mainly composed of polymer resins, and the two differ significantly in chemical composition and physical properties.   1. Chemical composition From a chemical composition perspective, the main structure of silica gel is a main chain connected by silicon oxygen bonds, without a carbon carbon main chain, which allows it to maintain stability between -60 ℃ and 200 ℃; The main chain of plastic is a high molecular weight resin with a carbon carbon structure, such as polyethylene and polypropylene, which are prone to softening and deformation at high temperatures. The performance of most plastics will be compromised at temperatures above 80 ℃. DiBo Company found through testing that the molecules of silicone are much more stable than ordinary plastics, so they are not easily deformed at high temperatures. 2. Performance characteristics In terms of performance, the difference between the two is more pronounced. Silicone has good elasticity and can quickly return to its original shape after being pulled. It is not easy to age, not afraid of sunlight, and will not harden or crack after a long time of use; There are two types of plastics: thermoplastic and thermosetting. Thermoplastic plastics can be processed repeatedly, but they have poor elasticity and are prone to breakage under stress. They can also oxidize and become brittle and discolored after being exposed to the sun for a long time. Dibo Company has conducted experiments and found that good silicone products can last for 5 to 10 years, while ordinary plastics generally age significantly in the same environment after 2 to 3 years. In addition, silicone is not harmful to the human body, it is non-toxic and odorless, and can directly come into contact with food and skin; Some plastics contain harmful substances such as plasticizers and bisphenol A, which may affect health if exposed to them for a long time. This is also the reason why silicone is more commonly used in mother and baby products and medical fields. When purchasing specific products, one should choose according to their corresponding needs, as performance characteristics still have a significant impact on product usage. 3. Place of use Where they are used differently is precisely because of their different characteristics. Silicone is resistant to high and low temperatures, not easily aged, and has good flexibility. It is commonly used in sealing components for kitchen utensils, medical equipment, and electronic parts. The silicone sealing rings made by Dibo Company for many home appliance companies have been recognized for their good sealing and strong temperature resistance; Plastic has low cost, easy processing, and adjustable hardness, and is more commonly used in packaging materials, toy casings, and daily necessities. In terms of resisting chemical substances, silicone has a stronger resistance to acids, bases, and organic solvents, while plastics are easily corroded by specific chemicals. For example, polyethylene plastics may expand when exposed to alcohol, while silicone does not.   The differences in chemical composition, properties, and applications between silicone and plastic make them suitable for different scenarios. When selecting materials, consideration should be given to the usage environment and performance requirements. Although silicone is more expensive, it has advantages in durability and safety. Plastic is more competitive in terms of cost-effectiveness and processing diversity. Understanding these differences can help us choose materials more reasonably and maximize their effectiveness.

Why can silicone products achieve natural and pollution-free? In today's increasingly conscious environment of environmental protection and health, silicone products have become the preferred material in food, medical, maternal and child fields due to their "natural and pollution-free" characteristics. Its safety not only stems from the chemical stability of raw materials, but also runs through the entire chain of production processes, usage scenarios, and recycling processes. Deeply analyze the environmental advantages of silicone products from four dimensions: material properties, production processes, environmental performance, and application scenarios.   1. Material characteristics: The natural advantages of organic silicon compounds The core component of silicone is polysiloxane (- Si-O-Si -), which is composed of silicon (Si), oxygen (O), carbon (C), and hydrogen (H) elements. Its chemical structure is stable, insoluble in water and any solvent, and does not react with substances other than strong bases and hydrofluoric acid. This characteristic determines that silicone products have the following advantages: Non toxic and harmless: Silicone products will not release harmful substances in high temperatures or extreme environments. For example, food grade silicone gel can remain stable at high temperatures of 220 ℃, while medical grade silicone gel needs to pass ISO10993 certification to ensure no biological toxicity when in contact with the human body. High biocompatibility: The soft touch of silicone is similar to that of human skin, and it is widely used in scenarios such as baby pacifiers and human implants. For example, silicone pacifiers can simulate the touch of breast milk and are resistant to high temperature disinfection to prevent bacterial growth. Strong weather resistance: silicone products are UV resistant and anti-aging, and do not change color or embrittlement when used in outdoor environment for a long time. For example, silicone outdoor seals can maintain elasticity even at extreme temperatures (-40 ℃ to 230 ℃). 2. Production process: dual guarantee of environmental protection and safety The production process of silicone products follows the principle of green manufacturing, strictly controlling environmental indicators from raw material processing to finished product delivery High temperature curing process: Silicone is cured and formed at high temperatures using a vulcanizing agent, with no harmful substances remaining throughout the entire process. For example, quinone compounds or metal oxides used in the vulcanization process react completely under high temperature and pressure without releasing toxins. Low energy consumption and low emissions: Silicone production does not rely on petroleum resources, and the main raw material, quartz sand, has abundant reserves, with minimal environmental impact from mining. In addition, silicone products do not produce wastewater or exhaust gas during the production process, which meets green manufacturing standards. Strict quality testing: Food grade silicone gel must pass international certifications such as FDA and LFGB to ensure that the content of harmful substances such as heavy metals and plasticizers is below the safety threshold. For example, silicone tableware needs to undergo multiple tests such as high temperature resistance, acid and alkali resistance, and wear resistance before leaving the factory. 3. Environmental performance: Sustainable throughout the entire cycle from production to recycling The environmental friendliness of silicone products is not only reflected in the usage stage, but also throughout their entire lifecycle: Degradability: Silicone products can gradually degrade through microbial action in the natural environment, ultimately transforming into harmless substances. For example, discarded silicone seals can be decomposed by microorganisms in landfills, reducing pollution to soil and water sources. Recyclability: Silicone materials have high thermal stability and can be recycled through pyrolysis, incineration, and other methods. For example, silicone products can be converted into raw materials such as silicone oil and silicone rubber during the recycling process, achieving resource recycling. Durability and Reusability: Silicone products have good elasticity, strong wear resistance, and a service life of several years. For example, silicone kitchenware can be repeatedly cleaned and disinfected, reducing the use of disposable plastic products. 4. Application scenario: Environmental protection solutions covering multiple fields The environmental characteristics of silicone products make them a substitute for traditional materials in multiple fields: Food contact field: Silicone tableware, kitchenware, fresh-keeping boxes, etc. can directly contact food and are resistant to high and low temperatures. For example, silicone cup lids can be heated in a microwave without releasing harmful substances, while also having leak proof and insulation functions. In the field of healthcare, silicone catheters, prostheses, surgical instruments, etc. are widely used due to their biocompatibility and sterility. For example, silicone medical catheters can reduce patient allergic reactions and can be professionally processed, recycled, and reused after use. In the field of maternal and child products, silicone milk bottles, dental glue, toys, etc. have high safety and are suitable for use by infants and young children. For example, silicone gum can withstand baby bites and is made of soft material that does not damage the gums. In the industrial and electronic fields, silicone seals, buttons, protective covers, etc. have waterproof, dustproof, and earthquake resistant properties. For example, silicone phone cases can effectively cushion the impact of falling and remain unchanged after long-term use.   In summary, the "natural and pollution-free" characteristics of silicone products stem from the chemical stability of their materials, environmentally friendly production processes, full lifecycle sustainability, and wide range of application scenarios. From baby pacifiers to medical implants, from kitchen supplies to industrial seals, silicone products are driving multiple industries towards green manufacturing with their advantages of safety, environmental friendliness, and durability. With the development of new materials such as bio based silicone and smart silicone, the environmental performance of silicone products will be further improved, providing more solutions for human life and environmental protection.

How to customize high-quality silicone products? Silicone products have become core components in medical devices, food packaging, electronic devices, and other fields due to their high and low temperature resistance, chemical stability, and biocompatibility. However, customizing a silicone product that meets the requirements is not an easy task - according to statistics, about 60% of customization failure cases are due to unclear communication of requirements or improper process selection. From precise demand matching to the application of materials science, and then to the collaboration between precision molds and production processes, each link profoundly affects the performance and reliability of the finished product.   1. Requirement analysis: the cornerstone of successful customization At the beginning of customization, it is necessary to clarify the product's functional parameters and application scenarios. For example, medical grade silicone gel needs to comply with ISO 10993 biocompatibility standards, while food contact products need to meet FDA or LFGB certification. Customers are required to provide detailed dimensional tolerances (usually ± 0.1mm), hardness range (Shore A 20-80 degrees), temperature resistance performance (such as -60 ℃~300 ℃), and other data. Manufacturers need to design based on production feasibility assessment, such as avoiding thin-walled structures smaller than 0.5mm to reduce the risk of cracking, or optimizing the demolding slope to simplify the manufacturing process.   2. Material selection: Balance between performance and safety The silicone material directly determines the safety and durability of the product: Ordinary silicone: suitable for non-contact scenarios such as industrial seals and buttons, with low cost; Food grade silicone: certified by FDA 21CFR177.2600, used for tableware and baby products; Medical grade silicone: requires sterile treatment and biocompatibility testing, suitable for implantable devices; Special silicone: such as conductive silicone (used for electronic shielding) or flame-retardant silicone (used in fire-resistant scenarios). When selecting materials, it is necessary to weigh the physical property indicators - for example, oil resistant seals require a tensile strength of ≥ 8MPa, while high-frequency silicone buttons need a tear resistance strength of 25KN/m or more. 3. Mold development and production process: the core of precision manufacturing Mold accuracy is the key to quality assurance. The design of the parting surface needs to avoid the external view, and complex structures require the use of sliding blocks to assist in demolding, with a 0.5% mold repair allowance reserved. The choice of mold material also affects the lifespan: aluminum alloy molds (delivered in 7 days) are suitable for small-scale trial production, while stainless steel molds (with a lifespan of over 100000 times) are suitable for large-scale production. The production process requires strict control of process parameters: Solid silicone molding: Low cost but low efficiency, suitable for thick walled parts. Post processing includes freezing to remove burrs (burrs ≤ 0.1mm), secondary vulcanization to improve physical properties, and UV spraying to enhance surface wear resistance.   Customized silicone products are a systematic engineering that integrates material science, precision engineering, and quality management. From demand anchoring to mass production delivery, only by selecting suppliers with interdisciplinary technical capabilities (such as mold flow analysis, automated production) and complete certification (ISO 13485, etc.) can design defects and process risks be avoided, achieving the optimal balance between cost, efficiency, and quality.

What are the types of silicone seals? In modern industry, silicone seals are highly regarded for their excellent performance and wide range of applications. As an important sealing component, silicone sealing rings play an irreplaceable role in various devices due to their diverse types and unique material properties.   There are various types of silicone seals, which can be classified into different types based on their shape, purpose, and characteristics. Among them, the most common is undoubtedly the silicone O-ring seal. O-ring has a circular cross-section, simple structure, and easy installation, making it the preferred choice for sealing requirements of various equipment. O-ring is mainly used for static sealing and reciprocating sealing, but when used for rotary sealing, it is limited to low-speed rotary sealing devices. In addition, silicone U-shaped, Y-shaped, V-shaped, rectangular sealing rings, etc. also have their own characteristics. U-shaped sealing rings are commonly used to manufacture reciprocating seals in hydraulic systems and are widely used for sealing hydraulic cylinders in construction machinery. Y-shaped sealing rings are widely used in reciprocating sealing devices. V-shaped sealing ring is an elastic rubber sealing ring with axial action, used as a non pressure seal for rotating shafts. Its sealing lip has good mobility and adaptability, and can compensate for large tolerances and angular deviations. Rectangular sealing rings are generally installed in grooves with rectangular cross-sections on the outer or inner circle to provide sealing function.   In addition to basic shape classification, silicone seals can also be further subdivided into various types based on usage conditions. High temperature resistant silicone sealing rings can maintain stable sealing performance in high-temperature environments and are suitable for applications with high temperature requirements. Food grade silicone sealing rings are widely used for sealing packaging containers and pipeline systems in industries such as food and medicine due to their non-toxic, odorless, and corrosion-resistant properties. Gas phase silicone sealing rings have excellent breathability and selectivity for gas permeation, making them suitable for sealing applications that require gas exchange. The conductive silicone sealing ring achieves appropriate conductivity by adding conductive materials such as conductive carbon black, nickel powder, aluminum powder, silver powder, etc., and is suitable for occasions that require conductive sealing.   In addition to the common types mentioned above, there are also some special types of silicone seals worth paying attention to. High tensile silicone sealing rings are processed with special formulas and techniques to provide higher tensile strength and tear resistance, making them suitable for applications that require significant mechanical stress. The ozone resistant silicone sealing ring is specially designed for ozone environments, which can maintain stable sealing effect for a long time in environments with high ozone concentration. In addition, there are tear resistant silicone seals and other materials, each with unique performance advantages to meet the special needs of different industries and working conditions.   The reason why silicone sealing rings stand out among many sealing components is due to their unique material properties. The main component of silicone sealing ring is silicone, and the molecular main chain of silicone is composed of alternating silicon atoms and oxygen atoms. It is a high molecular elastic material with both inorganic and organic properties. The molecular structure of silicone gives it excellent heat resistance, low-temperature elasticity, and resistance to oxidation and ozone. In addition, silicone sealing rings also have good electrical insulation performance, corona resistance, and arc resistance, which can maintain stable sealing effect in various harsh environments. At the same time, silicone sealing rings also have high breathability and selectivity for gas permeation, and can be customized according to specific needs.   The application field of silicone sealing rings is extremely wide, covering almost all industrial scenarios that require sealing protection. In hydraulic transmission systems, silicone sealing rings are often used for sealing hydraulic cylinders. Their good sealing performance and high pressure resistance can effectively prevent hydraulic oil leakage and ensure the stable operation of the system. In the automotive industry, silicone sealing rings are widely used for sealing key components such as engines and transmissions, preventing leakage of lubricating oil, coolant, and other liquids, ensuring the safety and reliability of automobiles. In addition, silicone sealing rings are highly favored in industries such as food and medicine due to their non-toxic, odorless, and corrosion-resistant properties, and are used for sealing various packaging containers and pipeline systems. At the same time, silicone sealing rings can also be used for sealing needs in industries such as aerospace, electronics, and chemical engineering, providing strong guarantees for the stable operation of various equipment.

What material is the mold for silicone products made of? In the production process of silicone products, the mold is a crucial tool that directly determines the shape, size, and accuracy of the product. In the selection of mold materials, different materials will bring different characteristics and applicable ranges.   Mold material for silicone products There are various types of mold materials for silicone products, including the following: Aluminum alloy mold Aluminum alloy molds are a commonly used type in the production of silicone products. It has the advantages of good thermal conductivity, high strength, and light weight, making it suitable for making small and medium-sized silicone products with simple structures. The processing accuracy of aluminum alloy molds is high, which can meet the strict requirements of silicone products for size and shape. Steel mold Steel molds are commonly used to make large or structurally complex silicone products. Steel has high hardness and wear resistance, and can withstand significant pressure and wear, so the service life of steel molds is relatively long. However, the processing cost of steel molds is relatively high, and their weight is large, which is not conducive to handling and operation. resin mold Resin molds are commonly used in some small-scale production or sample making due to their low cost and ease of processing. The molding speed of resin molds is fast, and they can quickly produce the required mold shape. However, the strength and wear resistance of resin molds are relatively poor, making them unsuitable for long-term high-intensity use. Silicone mold (for replication) It is worth noting that silicone is also used as the mold material during the replication process of silicone products. This type of silicone mold is usually formed by injecting liquid silicone into the surface of the prototype and curing it, which has the advantages of good elasticity, easy demolding, and reusability. Silicone molds are particularly suitable for making silicone products with complex structures and rich details. The selection of mold material for silicone products has a significant impact on product quality and production efficiency. When selecting mold materials, it is necessary to comprehensively consider factors such as specific product requirements, production scale, and budget.

Which is stronger and more durable, PVC or silicone? Both of them have their own abilities, but overall, silicone is more durable. Silicone has stable chemical properties, good physical properties, and is not easily aged or worn out; PVC has decent hardness and impact resistance, but its performance may decrease over time due to environmental factors. 1.Is the material stable, resistant to sunlight and heat? The molecular structure of silicone is unique and its chemical properties are particularly stable. It is not afraid of cold or heat (from minus 40 degrees Celsius to over 200 degrees Celsius), and it is not easily cracked, hardened, or brittle under wind, sun, or ozone environments. Silicone sealing rings can maintain elasticity even after being used on high-temperature equipment for 3 years; But the same PVC sealing ring, under the same conditions, will harden after about a year of use. PVC contains chlorine, and if it is exposed to temperatures above 60 degrees Celsius or direct sunlight for a long time, it is prone to damage, releasing a gas that can cause the material to become brittle and crack. For example, outdoor PVC water pipes may age and leak after 3-5 years of use, while silicone water pipes can last 8-10 years in the same environment. 2.Will it deform if it is wear-resistant or not? Silicone has a dense molecular structure and is also very elastic. After being ground or compressed, it can quickly return to its original state without leaving permanent deformation. Under the same pressure, silicone products can be ground 100000 times, with only slight scratches on the surface; But after grinding PVC products for about 50000 times, there are obvious scratches and pits. PVC has a high hardness (similar to that of a plastic ruler), and its impact resistance is better than silicone in a short period of time, but it is more brittle and easily broken by a strong impact. For example, children's toys, silicone dolls, are still in good condition after being thrown around; Toys made of PVC may crack at the corners. 3.Are you afraid of chemical corrosion? Silicone is not afraid of acids, alkalis, oils, and other substances. It will not swell or deteriorate when in contact with cleaning agents or cosmetics. Silicone has been exposed to oil stains and hot detergent for a long time, and its performance has not changed much. PVC is afraid of organic solvents, such as alcohol and gasoline, which can become soft, swollen, and even melt off when touched. For example, if the PVC keychain is stained with nail polish, the surface will become sticky and deformed soon. 4.How should I choose? If it is used outdoors for a long time, in high temperature environments, or frequently in contact with chemicals (such as sealing rings, high-temperature resistant parts), choosing silicone is more durable; If it is for short-term use, requires high hardness, and has a relatively stable environment (such as hard pipes, cheap daily necessities), PVC can also meet basic needs. The choice of materials depends on the specific application: if long-term durability and stability are important, silicone is preferred; If you want to save money and use it in the short term, and need high hardness, then PVC can be considered. These two materials each have their own advantages, but in terms of overall strength and durability, silicone is better able to withstand the test of time and environment.

What are the coloring processes for silicone products? Silicone products are widely used in daily life and industrial production due to their softness, durability, and environmental friendliness. In order to meet the diverse needs of different customers for product appearance, the coloring process of silicone products is particularly important. Appropriate coloring techniques can not only enhance the aesthetic appeal of products, but also strengthen their market competitiveness.   Common coloring techniques for silicone products 1. Screen printing process Screen printing is a commonly used technique for coloring silicone products. It uses silk screen as the printing base and is made into a silk screen printing plate with graphics and text by photosensitive plate making method. During printing, a scraper is used to press and transfer ink through the mesh holes of the graphic and text parts to the surface of the silicone product, thereby forming the same graphic and text as the original. The advantage of screen printing technology is that it can achieve high-precision pattern printing, with bright and full colors, and can print a variety of complex patterns and text. However, the silk screen printing process has a relatively weak effect on the layering and three-dimensional sense of the pattern, and there may be uneven color distribution when coloring on a large area. 2. Spray coating process The spraying process is a coating method that uses a spray gun or disc atomizer to disperse the coating into uniform and fine droplets under pressure or centrifugal force, and apply them to the surface of silicone products. This process can achieve uniform coloring over a large area and quickly cover the entire surface of silicone products, resulting in good color consistency of the product. The spraying process can also create a smooth and delicate surface effect, enhancing the texture of the product. But it also has some shortcomings, such as relatively low utilization rate of coatings, which may result in some waste of coatings; Moreover, during the spraying process, improper operation can easily lead to defects such as sagging and orange peel. 3. Transfer printing process Pad printing is an indirect concave adhesive head printing technology. First, etch the designed pattern onto a printing plate, apply ink to the etching plate, and then transfer most of the ink onto the surface of the silicone product through a silicone head. The advantage of transfer printing technology is that it can print on the surface of irregularly shaped silicone products, with strong adaptability, and can print fine patterns and text, especially suitable for products with curved or uneven surfaces. However, the production efficiency of transfer printing technology is relatively low, and for multi-color printing, multiple transfer prints are required, which may affect the accuracy of pattern registration. 4. Immersion dyeing process The immersion dyeing process involves immersing silicone products in a solution containing dyes, allowing the dyes to gradually penetrate into the interior of the silicone, thereby achieving the purpose of coloring. This process has uniform coloring, and the color can penetrate deep into the interior of silicone products, which is not easy to fade and has good washing and friction resistance. The immersion dyeing process is commonly used for some silicone products that require high color durability, such as silicone bracelets, silicone keychains, etc. However, the color selection of immersion dyeing process is relatively limited, mainly suitable for some dark colors, and it is difficult to achieve complex patterns and texts through immersion dyeing process.   Preparation before coloring silicone products 1. Surface treatment of silicone products Before coloring, it is necessary to clean the surface of silicone products to remove oil stains, dust, impurities, etc., to ensure that ink or paint can adhere well to the silicone surface. You can use specialized cleaning agents for cleaning, then rinse with clean water and air dry. For some silicone products with rough or rough surfaces, polishing treatment is also needed to make the surface smooth and flat. 2. Ink or coating selection Choose the appropriate ink or coating based on the selected coloring process and the requirements for the use of silicone products. Consider factors such as ink or coating adhesion, weather resistance, wear resistance, and environmental friendliness. For example, for silicone products used outdoors, it is necessary to choose inks or coatings with good weather resistance to ensure that they do not fade easily after prolonged exposure to sunlight. At the same time, it is important to ensure that the selected ink or coating is compatible with silicone material and does not undergo chemical reactions. 3. Color adjustment According to the color samples or color cards provided by the customer, use color matching equipment to mix ink or paint into the desired color. During the color mixing process, it is necessary to accurately control the proportion of various pigments, and through multiple color tests and adjustments, ensure that the blended color is consistent with the target color. After color matching is completed, the ink or coating should be stirred evenly to ensure color consistency.   Coloring process for silicone products 1. Positioning and fixation Place the silicone product to be colored on the workbench of the coloring equipment, and accurately position and fix it to ensure that the silicone product does not move during printing or spraying, thereby ensuring the accuracy and quality of coloring. Special fixtures or positioning devices can be used to fix silicone products. 2. oloring operation Screen printing: Install the prepared screen printing plate on the screen printing machine and adjust the distance and angle between the plate and the silicone product. Pour the prepared ink into the ink tank of the screen printing machine, start the screen printing machine, and transfer the ink through the mesh to the surface of the silicone product through the squeezing of the scraper. After printing is completed, take out the silicone product for inspection and reprint if necessary. Spraying: Connect the spray gun to the air compressor, adjust the spray amplitude, air pressure, and paint output of the spray gun. Pour the prepared coating into the coating cup of the spray gun, hold the spray gun in hand, maintain an appropriate distance and angle from the surface of the silicone product, and evenly spray the coating. During the spraying process, attention should be paid to the speed and direction of the moving spray gun to avoid uneven coating. Pad printing: Install the etching plate on the pad printing machine, apply an appropriate amount of ink on the etching plate, and then use a scraper to scrape off excess ink, leaving only the graphic and text parts. Press the silicone head onto the etching plate to transfer ink onto the silicone head. Move the silicone head onto the surface of the silicone product and gently press to transfer the ink onto the silicone product. Dip dyeing: Pour the prepared dye solution into the dip dyeing tank and control the temperature and concentration of the solution. Slowly place the silicone product into the immersion tank and soak for a period of time to allow the dye to fully penetrate into the interior of the silicone. After soaking, remove the silicone product and rinse it with clean water to remove excess dye on the surface. 3. Drying and curing After coloring is completed, the silicone product needs to be dried and cured to firmly adhere the ink or coating to the surface of the silicone. The drying method can be selected based on the properties of the ink or coating, such as natural drying, hot air drying, or ultraviolet curing. Natural drying time is longer, but the cost is lower; Hot air drying can accelerate the drying speed, but it is necessary to control the temperature well to avoid deformation of silicone products caused by excessive temperature; UV curing is suitable for some UV curable inks, with fast curing speed and high efficiency.

Why has silicone sealing ring become a key material in modern times? In medical equipment, household appliances, and industrial machinery, a seemingly inconspicuous component is quietly playing an important role - silicone sealing ring. It is not only the core component that ensures the sealing performance of equipment, but also the bridge that connects technological progress with safety requirements. From precise oxygen supply for home ventilators to efficient operation of car engines, silicone seals have become an indispensable material in modern industrial and medical fields due to their excellent high temperature resistance, aging resistance, and biocompatibility. The core value of silicone sealing rings lies in their unique material properties. Firstly, it has excellent temperature resistance and can work stably for a long time in the extreme temperature range of -60 ℃ to 200 ℃. Even special formula products can withstand high temperatures up to 300 ℃. This characteristic makes it perform excellently in high-temperature environments such as automotive engines and aerospace equipment. In terms of application scenarios, the permeability of silicone sealing rings continues to increase. In the field of household appliances, the sealing demand for products such as rice cookers, water dispensers, and coffee makers has driven the popularity of silicone sealing rings, whose non-toxic and odorless characteristics meet food contact safety standards. In the medical field, with the outbreak of the home ventilator market in the post pandemic era, the market share of silicone sealing rings is expected to grow from 60% in 2024 to 55% in 2030, and the market size is expected to exceed 330 million US dollars. In the industrial field, emerging application scenarios such as battery pack sealing for new energy vehicles and protection for photovoltaic equipment have further expanded demand. Data shows that the market size of silicone seals in China has reached 8.5 billion yuan in 2024, and is expected to exceed 13.5 billion yuan by 2030, with an average annual compound growth rate of 9.7%. In the future, the development of silicone sealing rings will focus on three major directions: high-performance, intelligent, and environmentally friendly. In terms of high performance, the company improves the tensile strength to over 10MPa and maintains a fracture elongation of over 400% by optimizing the formula, in order to extend the product life. Intelligence is reflected in integrated sensor technology, which improves the safety of equipment operation by real-time monitoring of sealing status and warning of abnormalities. In terms of environmentally friendly manufacturing, the industry is promoting the use of biodegradable additives and the development of clean production processes to reduce pollution during the production process. In addition, breakthroughs in 3D printing technology have provided new possibilities for customized sealing rings.

Silicone sealing rings, with their irreplaceable performance advantages, will continue to play a key role in fields such as new energy vehicles, medical equipment, and intelligent manufacturing, becoming the core force driving high-quality development in the industry.

How to prevent oxidation of silicone products? Silicone products have become an indispensable material in daily life and industrial production due to their environmental friendliness, high temperature resistance, softness, and durability. However, problems such as yellowing and hardening caused by oxidation have been a headache for many users. From oxidation principles, preventive measures, daily maintenance to purchasing skills, we provide comprehensive knowledge of silicone products to help you easily extend product life.   Silica gel oxidation is the result of long-term interaction between materials and the external environment, mainly influenced by the following factors: Ultraviolet attack: Ultraviolet (UV) rays in sunlight can damage the molecular chains of silica gel, triggering oxidation reactions and generating yellowish substances. For example, phone cases and outdoor items that are left by the window for a long time are often more prone to oxidation. Oxidation and pollution: Acidic substances in sweat and cosmetics penetrate the pores of silicone gel, accelerating oxidation; Ozone in the air and free radicals in car exhaust can also directly erode the surface of materials. Material defects: Cheap silicone may contain unstable additives such as sulfides and plasticizers, which can easily decompose and turn yellow; Incomplete vulcanization leads to loose molecular structure and poor anti-aging ability. Extreme environment: High temperature, humidity, or long-term exposure to chemicals can accelerate the breakage of silicone molecular chains, leading to a decrease in performance.   Four Steps to Anti Oxidation: From Selection to Daily Care 1. "Polish your eyes" when making a purchase Priority should be given to high transparency raw materials: high-quality silicone raw materials (such as inlet gas phase silicone) have more stable molecular structures and stronger resistance to yellowing. Pay attention to vulcanization process: vulcanization temperature and time directly affect product performance. Excessive mold temperature or insufficient vulcanization can easily cause molecular chain breakage and accelerate oxidation. Avoid the low price trap: Low priced silicone products may use recycled materials or inferior additives, which pose a higher risk of oxidation. 2. Storage environment: "Three Avoidances and Three Requirements" Avoid light: Store silicone products in a cool and dry place, away from direct sunlight or ultraviolet radiation. Avoid moisture: Maintain ventilation, stay away from damp environments, and prevent mold and deformation. Avoid chemical substances: Avoid contact with strong acids, bases, solvents, etc. to prevent corrosion. To seal: When not in use for a long time, seal with a dark sealed bag to reduce contact with oxygen. To isolate: Store separately from other items to prevent contamination or impact. Temperature control: The storage temperature should be controlled at around 20 ℃ to avoid extreme high or low temperatures. 3. Cleaning and maintenance are "gentle first" Regular cleaning: Gently wipe with warm water and neutral detergent (such as dishwashing detergent) to avoid damaging the surface with hard brushes or abrasive cleaners. Stubborn stain treatment: Dip a small amount of toothpaste or baking soda and gently rub, then rinse with clean water. Drying method: After cleaning, place in a cool and ventilated place to air dry naturally. Do not dry at high temperatures or expose to direct sunlight. 4. Targeted protection for special scenarios Outdoor products: Silicone products that are exposed to the outdoors for a long time (such as sealing rings and handles) can be coated with a small amount of food grade lubricant to form a protective film. Kitchen utensils: Silicone spatulas and baking molds that come into contact with grease should be cleaned immediately after use to avoid residue corrosion. Maternal and child products: pacifiers, dental implants, etc. need to be regularly disinfected at high temperatures, but the time and temperature should be controlled to avoid deformation.   The oxidation problem of silicone products is not unsolvable, the key lies in "prevention first, maintenance as a supplement". From selecting high-quality raw materials, controlling storage environment, to gentle cleaning and targeted protection, every step is related to product lifespan. Meanwhile, understanding the characteristics and cold knowledge of silicone products can help you better use and maintain them. Remember: Scientific maintenance of silicone products.

Customized development of silicone wristbands has become a hot topic, with various designs such as electronic design, functionality, quantum energy, etc. emerging in recent years. Different years have seen updates in appearance and functionality. With the rapid development of today, the definition of wristbands is no longer just a spiritual symbol of the past, but has gradually become a comfort that improves the quality of life! Is customizing a wristband really that troublesome? The answer is definitely negative. The first thing to consider is to define the raw materials and color structure in the later stage of the consumer market, and then evaluate whether the drawings can achieve the expected effect. The most important factor for customizing silicone bracelets is to consider cost and process selection. If a product is positioned at the low end but chooses a complex structure and process, it will probably be more troublesome! On the other hand, silicone wristband manufacturers need to assess the quality standards of their product manufacturing processes, such as self rewiring, product hardness and softness, and stretching strength, in advance. However, for the current silicone products industry, quality and testing requirements are explained in advance according to customer needs based on drawings, and a single line sampling is carried out to achieve the desired effect. Therefore, for customized silicone wristbands, besides the necessary investment, there is no need to worry about too many ideas. The most important thing is whether your product can meet market demand!
