In the process of customizing silicone products, material selection is the core link that determines product performance, usage scenarios, and final costs. Many users are not clear about the classification and differences of silicone materials, either blindly choosing high priced materials causing waste, or choosing low-priced materials that do not meet the usage standards. This article focuses on how to choose customized materials for silicone products, as well as the price differences corresponding to different materials, to help you accurately match needs, control budgets, and make cost-effective customization decisions. There are various types of silicone materials, mainly divided into three categories based on performance and application scenarios: industrial grade silicone, food grade silicone, and medical grade silicone. In addition, there are special modified silicone materials such as high temperature resistance, anti-static, conductivity, and high tensile strength. There are significant differences in environmental standards, temperature resistance range, hardness, elasticity, and safety among different materials, and their applicable industries are also different. The core principle of selecting materials is to match the usage scenario, meet safety and performance requirements, and not blindly upgrade or lower standards.Industrial grade silicone is the most basic silicone material, mainly used for non-contact human and non food contact scenarios such as electronic accessories, industrial sealing, shock absorption, dust prevention, etc. It has good insulation, aging resistance, and sealing properties, and its price is the lowest among the three types of materials. It is suitable for mass production and low-cost industrial product customization, with outstanding cost-effectiveness. Food grade silicone meets national food safety standards, is non-toxic, odorless, heat-resistant, corrosion-resistant, and can directly come into contact with tableware, mother and baby products, kitchen utensils, etc. It has higher safety and is priced higher than industrial grade silicone. It is the preferred material for the catering, mother and baby, and home appliance industries. Medical grade silicone has the strictest requirements, with biocompatibility, non allergenicity, non irritation, and is mostly used in medical consumables, beauty equipment, and human contact products. Its production process and testing standards are higher, so its price is also the highest.In addition to grade differences, silicone hardness, density, and special features can also affect customization prices. Conventional hardness silicone is moderately priced, while ultra-high or ultra-low hardness silicone requires special blending, which will increase the cost accordingly; Modified silicone with high temperature resistance of over 300 ℃, flame retardancy, and conductivity, due to more complex raw materials and processes, is priced higher than ordinary silicone. When customizing, the manufacturer will recommend suitable materials based on your usage scenario, such as food grade for mother and baby products, medical grade for medical products, and industrial grade for ordinary industrial seals.Choosing silicone material correctly can ensure product quality and usability, while also avoiding budget waste. If the wrong material is selected, the product may not meet the standard and cannot be used, and there may be safety hazards, resulting in rework and additional costs. It is recommended to clarify the usage environment, contact medium, safety standards, and temperature resistance requirements before customization, communicate with the manufacturer to confirm the material scheme, and then compare the corresponding quotation.

After the production of silicone products, there are many post-processing steps that can make the silicone products look more delicate in both feel and appearance. Today, we will introduce a silicone oil spraying process and the advantages of the sprayed product. The tactile oil sprayed on silicone products is also known as silicone matte oil or silicone matte oil. In fact, many silicone products require surface spray treatment. Silicone products that have undergone spray treatment generally have the following advantages. 1. The surface of the silicone product after spraying is relatively smooth, and it feels very delicate to the touch, perfectly solving the rough and astringent feeling of silicone products after molding. 2. Silicone products are prone to static electricity during the rubber mixing and molding process, which can easily adsorb dust during later use. Spraying a layer of hand feel oil can greatly reduce static electricity and avoid dust adsorption. 3. Silicone products sprayed with oil have friction and wear resistance, and long-term use will not cause wear, which can extend the service life of silicone products.

With the increasing popularity of silicone products, people's aesthetic standards have risen sharply, and the demand for silicone products has also increased. While ensuring quality, it is also necessary to increase the aesthetic standards for silicone products. Therefore, a new technology - drip glue technology - has emerged. The benefits of drip glue technology for silicone products are not only to protect the surface of the product from wear, but also to pursue high-quality and exquisite appearance of silicone products. It is not difficult to make a lifeless silicone product into a three-dimensional, concave convex appearance effect, and a few points need to be noted. 1. In the process of making dropper silicone products, it is necessary to ensure the cleanliness of all utensils during the dropper process to avoid impurities, ripples, and other defects on the surface after the glue solidifies. 2. In the process of making silicone products using the dropper process, the glue ratio must be accurately weighed, and the glue must be stirred evenly, otherwise it will cause incomplete dropper curing and prolonged curing. 3. The humidity of the glue dispensing working environment should be controlled at 68%. It is not recommended to perform glue dispensing work on rainy days because when the humidity in the air is too high, the mist in the air will directly cause the surface of the glue to oxidize. If the production task is tight, it is recommended to use an air dehumidifier. When producing silicone products with droppings, the silicone products are concentrated in the drying area and the temperature is controlled between 28 ° -40 ° C to ensure that the droppings are of good quality and reduce the defect rate.

In the field of polymer materials, silicone and rubber are well-known materials, but the question of whether silicone belongs to a type of rubber often sparks discussion. To accurately answer this question, it is necessary to analyze from multiple dimensions such as the chemical structure, performance characteristics, and processing methods of the material. From the essence and definition of materials, silicone belongs to a special category of rubber, scientifically known as "silicone rubber". Rubber usually refers to a highly elastic polymer material with reversible deformation, which is elastic at room temperature and can produce significant deformation under very small external forces. After removing the external forces, it can restore its original state. Silicone possesses typical characteristics of these rubbers, but its molecular structure and properties differ from traditional rubbers. Ordinary rubber is mainly composed of elements such as carbon and hydrogen, while the main component of silicone is polysiloxane, with silicon oxygen bonds as the main chain structure. This makes silicone more excellent in high temperature resistance, low temperature resistance, weather resistance, electrical insulation, and other aspects.In terms of high temperature resistance, ordinary rubber is prone to aging, deformation, and even decomposition in high-temperature environments. Silicone can be used for a long time in high temperature environments above 200 ℃, and some specially formulated silicone can withstand higher temperatures. This characteristic makes it play an important role in high-temperature working scenarios such as aerospace and automotive engines. In terms of low temperature resistance, silicone can still maintain good elasticity and flexibility even under extreme cold conditions of -60 ℃. In contrast, many ordinary rubbers become hard, brittle, and lose their elasticity at low temperatures. In addition, silicone has excellent weather resistance, with minimal performance changes and a long service life when exposed to natural environments such as ultraviolet radiation, ozone, and wind and rain for a long time. It has significant advantages in outdoor sealing components, building materials, and other fields. From this, it can be seen that although silicone has similarities with rubber in terms of elasticity, it does not fully belong to the traditional category of rubber based on comprehensive factors such as chemical structure, performance characteristics, and processing methods.

The application range of silicone plugs is extremely wide. In the field of daily life, it is the "capable assistant" of kitchen supplies. Various wide mouthed bottles, storage tanks, and hot water kettles are often equipped with silicone stoppers, which utilize their excellent sealing performance to isolate air and moisture, extend the shelf life of food, and prevent seasoning from getting damp and clumping. In the beauty and skin care industry, containers such as face cream bottles and essence bottles can not be sealed without silicone plugs, which can effectively prevent the volatilization and oxidation of the contents and maintain the stability of product quality. In the industrial field, silicone plugs also perform well. During the manufacturing process of electronic devices, silicone plugs are used to protect the sockets of circuit boards and interfaces of instruments from dust and water, in order to prevent equipment failure caused by external impurities; In automobile manufacturing, silicone plugs are used to seal oil and gas interfaces, ensuring stable operation of automotive systems and improving safety and durability.The reason why silicone plugs can establish themselves in many fields is closely related to their significant advantages. From the perspective of material characteristics, silicone has good high and low temperature resistance, and can maintain stability in the temperature range of -60 ℃ to 200 ℃. Whether it is a hot water kettle or a low-temperature refrigerated container, silicone plugs are capable of sealing work. At the same time, silicone material is non-toxic, odorless, environmentally friendly, and meets food grade and medical grade standards, which is also the key to its wide application in kitchen, medical and other fields. In addition, silicone plugs have excellent elasticity and can tightly fit the container mouth, forming an effective sealing effect. They also have excellent aging resistance and are not easily deformed or cracked after long-term use.

The silicone button spray process is the core technology for improving product texture, touch, and lifespan, with significant differences between different processes. Based on industry demand, we will provide a detailed breakdown of the core characteristics, advantages and disadvantages, and applicable scope of mainstream processes to assist in precise selection.The silicone button spray process can be divided into three directions based on function: color expression, tactile enhancement, and high-end protection. It can be used alone or in combination to achieve dual improvement in appearance and performance.Firstly, there are color expression techniques, with the core of endowing buttons with rich colors to solve the problem of single color on silicone substrates, mainly including spray oil and two-color/multi-color spray oil.Spray oil is a basic and widely used process, which achieves customized colors by spraying colored oil-based ink on the surface of silicone gel, and can achieve luminous effects. Its color is full, can be freely adjusted, has low cost, and simple process; But it has poor wear resistance, is prone to color and oil loss, and has average adhesion. Suitable for civilian products such as TV remote controls, air conditioning buttons, etc. that require low wear resistance and focus on cost.Dual color/multi-color spray is an advanced process for spraying colored oil, which uses masking technology to spray different colors multiple times without the need for laser engraving to present a sense of layering. Its appearance is high-end and its appearance is outstanding, but the process is complex, the yield is low, the cost is high, and the wear resistance is not as good as high-end protective processes. Suitable for high-end products such as game controllers and smartwatches that emphasize appearance.Secondly, there are techniques for improving the tactile sensation, with the core being to optimize button touch and create a skin friendly and anti slip experience, mainly including spraying tactile oil and rubber oil.Spray feel oil, also known as matte oil spray, forms a micro matte coating by spraying matte ink, presenting a matte effect, not sticking to fingerprints, with a delicate and smooth touch, and good anti slip properties. It has a good hand feel, high cost-effectiveness, and can be reworked, but long-term friction can easily wear and expose the bottom. Suitable for high-end rice cookers, Bluetooth earphones, and other experiential home appliances and digital products.Spraying rubber oil is a high-end tactile process, using high elasticity rubber coating to present a deep matte texture, with a soft and elastic touch and optimal anti slip performance. It has excellent tactile sensation and enhances the high-end feel of the product, but it is costly, difficult to process, and prone to peeling and detachment due to inadequate pre-treatment, which is greatly affected by the environment. Suitable for high-end products such as car air conditioning knobs and high-end game controllers.Finally, there is the high-end protective technology, which focuses on solving the pain point of silicone buttons not being wear-resistant. The mainstream technology is spraying PU oil.Spraying PU oil, also known as polyurethane spraying, forms a high-strength protective coating, mostly transparent or semi transparent matte, with a dry and solid touch. It has super strong wear resistance, good chemical resistance, and strong adhesion, and requires corona/plasma treatment; But the cost is high, cannot be reworked, and has extremely high requirements for the production environment. Suitable for products with high durability requirements such as car keys and industrial machinery keyboards.In actual production, different processes can be combined to meet the requirements of color, touch, and wear resistance. Process selection should be based on product positioning, usage scenarios, and cost budgets to accurately match production needs.

Firstly, the production process of silicone buttons requires the design of drawings. Based on the appearance of the product, a model is created and a drawing that matches the product is drawn. Then, we will find someone to create a mold according to the drawing. When producing silicone buttons, steel molds are used to make the product more elastic and durable. The next step in making a good mold is to mold the silicone button. During the molding process, it is important to control the temperature of the mold properly, and the temperature must not be too high or too low. If the temperature is too low, it will cause the molded product to have immature rubber. Also pay attention to the feeding issue. Do not put too much material in, as too much material can cause burrs that are difficult to remove and easily tear the product. After removing the burrs, an important part of the product is the process of laser engraving various patterns, because silicone buttons have a basic performance of being transparent, so laser engraving is also very important. Currently, many silicone buttons are made in transparent colors, which are more translucent. The process involves spraying white oil, printing color blocks with patterns, spraying black oil, and laser engraving patterns. There are four steps in the process, each of which cannot be omitted. If there is a problem in any link, the entire product will be scrapped. In terms of laser engraving of silicone buttons, our technology is gradually improving to save customers more costs and make better products.

Are silicone products safe and environmentally friendly? Driven by both health awareness and environmental protection needs, silicone products have gradually penetrated into daily life scenarios such as food contact, medical health, maternal and child care, and electronic protection due to their unique material properties. As a polymer silicon oxygen bond compound, silicone gel has become a substitute for traditional plastics due to its core advantages of temperature resistance, chemical stability, and biocompatibility. 1. Safety certification: strict control from laboratory to daily lifeThe safety of silicone products comes from the endorsement of certification systems in multiple countries around the world.Medical grade silicone needs to pass ISO 10993 biocompatibility testing and be used in implantation scenarios such as artificial joints and pacemaker insulation layers. Clinical data shows that patients using silicone implants have a 35% reduction in postoperative discomfort rates and a 50% extension in product lifespan. It should be noted that industrial grade silicone contains additives such as flame retardants and vulcanizing agents, and is strictly prohibited from coming into contact with food or human body. Consumers need to distinguish product grades through certification marks (such as FDA, LFGB). 2. Environmental Value: A Green Closed Loop from Production to WasteThe environmental protection properties of silicone are reflected in its full lifecycle management. On the production end, its raw material is high-purity silica (sandstone extract), and the chemical synthesis process does not rely on petroleum resources. The platinum catalytic solidification process can reduce sulfide residue. On the user side, silicone products have a lifespan of up to 5-10 years, which is 3-5 times longer than plastic.In the waste disposal process, the degradation cycle of silicone in the natural environment is 2-5 years (500 years for plastics). After being buried in the soil, it undergoes microbial action, resulting in a mass loss of about 35% in 24 months. Eventually, it decomposes into water, carbon dioxide, and silica, with no residual microplastics. However, the global recycling rate of waste silicone gel is less than 15%, and due to the high cost of classified recycling, some mixed products can only be incinerated. To solve this problem, the laboratory is developing bio based silica gel for extracting silica from rice husks, which reduces carbon footprint by 50% and shortens the processing cycle to 6 months using enzymatic degradation technology. 3. Performance boundary: advantages and limitations in extreme environmentsSilicone has a temperature resistance range of -60 ℃ to 250 ℃, does not crack when frozen in liquid nitrogen, does not deform when baked in an oven, and has 25 times the UV aging resistance of plastic. Its chemical inertness makes it the preferred protective material for laboratory beaker covers and chemical plant sensors, with a weight loss of only 0.3% after soaking in concentrated hydrochloric acid for 72 hours.But silicone is not a universal material. High temperature limits (such as stir frying or near oven heating tubes) may release formaldehyde or plasticizers, so avoid contact with open flames. In terms of surface characteristics, silicone gel is prone to adsorbing milk stains and oils, and needs to be boiled and disinfected daily to prevent odors; Electrostatic adsorption of dust requires wiping with alcohol; Using a steering wheel cover in summer may result in stuffy palms due to poor heat dissipation. 4. Future Trends: Dual Breakthrough of Intelligence and SustainabilityIn terms of material innovation, the temperature sensitive color changing silicone cup lid can change color and prevent scalding according to the temperature of the beverage. The conductive silicone realizes the integration of flexible circuits for folding mobile phone hinges, and the self-healing coating allows scratches to heal within 24 hours. The application scenarios have been expanded to the forefront of medical technology, such as 3D printing of cell culture silicone scaffolds for artificial organs, and biodegradable silicone implants that naturally decompose within 2 years. Silicone products, with safety certification as the cornerstone, environmental value as the core, performance optimization as the support, and technological innovation as the driving force, are redefining the material standards of modern life. It is not perfect, but through strict certification screening, reasonable selection of usage scenarios, and technological iteration upgrades, its advantages can be maximized. From the kitchen to healthcare, from mother and baby to electronics, the popularity of silicone products is not only a reflection of consumer upgrading, but also a practice of humanity moving towards a healthier and more sustainable lifestyle. In the future, with the maturity of bio based materials and closed-loop recycling systems, silicone is expected to contribute a key force to global environmental protection.

In many scenes of modern industry and daily life, there is a seemingly insignificant but crucial material, which is silicone foam strip. Its porous polymer material based on silicone rubber, with its honeycomb closed cell structure and excellent performance, has become the "invisible guardian" in the fields of sealing, insulation, and shock absorption, silently guarding the stable operation of equipment and buildings. What is the function of silicone foam strip? Below, we will provide you with answers one by one. Firstly, the core value of silicone foam strips lies in their strong sealing ability. The sponge like porous structure gives it excellent resilience and flexibility, even when facing uneven and irregular installation surfaces, it can tightly adhere and seamlessly seal, effectively blocking the intrusion of external dust, water vapor, and rainwater. Whether it is long-term exposed building facilities or complex industrial workshops, it can build a stable protective barrier to protect precision components from corrosion and short circuits, achieving integrated protection against dust, water, moisture, and air tightness.At the same time, in addition to basic sealing, the performance of silicone foam strips in thermal insulation, vibration isolation and buffering is also impressive. The uniform and dense closed cell structure inside the material can effectively block heat conduction and convection, and has excellent thermal insulation effect. It can be widely used in temperature control scenarios such as insulation of new energy vehicle battery packs and protection of industrial high-temperature equipment. In addition, the porous structure has excellent energy absorption and buffering properties, which can effectively absorb vibrations and impact forces during equipment operation, reduce noise propagation, minimize losses caused by mechanical collisions, and protect precision instruments and structural components. Serve as a cushion and shock-absorbing layer in fields such as automotive, aerospace, and home appliances, enhancing product reliability and user experience.What is even more advantageous is that silicone foam strips have strong environmental adaptability and safety reliability. It can work stably in a wide temperature range of -60 ℃ to 250 ℃, with intermittent temperature resistance up to 350 ℃. It is also resistant to ozone and ultraviolet radiation, and is not easily deformed or cracked under outdoor and harsh working conditions. Environmentally friendly and non-toxic, in compliance with international standards such as ROHS and FDA, coupled with excellent flame retardancy and electrical insulation, it can be safely applied in high standard fields such as medical, food, and electricity.

How to efficiently customize silicone products? In high-precision fields such as new energy, healthcare, and electronics, silicone products have become the core material due to their high temperature resistance and strong insulation properties. However, as the demand for customization continues to grow, enterprises often find it difficult to accurately implement due to complex processes and high technical barriers. How to achieve efficient collaboration from requirement communication to finished product delivery. The primary step in customizing silicone products is to achieve precise demand. Enterprises need to clarify the application scenarios of their products, such as sealing components in medical equipment that meet biocompatibility standards, and electronic accessories that have specific requirements for conductivity or insulation. In addition, dimensional tolerances, color matching (such as Pantone color card numbers), and hardness parameters (Shore A) need to be quantitatively labeled to avoid production deviations caused by vague descriptions. If there are 3D drawings or physical samples, communication costs can be significantly reduced.The second step is mold design and optimization. The mold structure directly affects the precision and production efficiency of the finished product, and complex structures require the use of multi cavity molds or hot runner technology. Taking the sealing components of new energy vehicle battery packs as an example, the mold needs to balance large-sized molding and micrometer level sealing groove processing. Enterprises can use CAE simulation software to predict the flow state of silicone and correct design defects in advance.The sample confirmation process is a critical node in quality control. Enterprises need to conduct multidimensional testing on the first sample: appearance inspection should exclude defects such as bubbles and flying edges; Dimensional measurement requires the use of a coordinate measuring instrument to verify the tolerances of key parts; Functional testing focuses on indicators such as sealing and resilience.A standardized process system needs to be established during the mass production stage. Temperature, pressure, vulcanization time and other parameters must strictly follow the trial production verification results to avoid performance fluctuations caused by batch differences. For example, medical grade silicone products require dynamic vulcanization technology to ensure that the mechanical properties of the material do not deteriorate after sterilization treatment. At the same time, enterprises can introduce SPC statistical process control to monitor key quality characteristics in real time and control the defect rate below 0.1%.Finally, the packaging and delivery process must match the requirements of the end customer. Export products must comply with the ISO 11607 sterilization packaging standard, while high-end electronic accessories may require anti-static shielding bag packaging. A multinational automotive parts supplier has reduced the damage rate of silicone seals during transportation to 0.05% through customized pallet stacking solutions, significantly improving customer satisfaction. The essence of customizing silicone products is the combination of technical collaboration and process optimization. Through precise requirement definition, innovative mold design, rigorous sample verification, and intelligent production management, enterprises can not only shorten development cycles, but also establish technical barriers in segmented fields. With the rapid development of industries such as new energy and intelligent hardware, mastering efficient customization capabilities will become the core competitiveness for enterprises to seize the market.
