Silicone rubber O-ring is the most widely used sealing product, and its production process is relatively simple, using a variety of materials. 1.Due to different formulations of silicone rubber O-rings, the tightening and stretching amounts of silicone rubber O-rings produced by different manufacturers are also different. When a product is in a long-term compressed state, there will be a scenario of compressive stress relaxation, which gradually expands over time. The longer the time, the smaller the amount of compression and stretching, resulting in insufficient elasticity and leakage. The most direct method is to increase the cross-sectional size of the product, but it can also lead to an increase in the structural size of the product.2.The correlation between temperature and the relaxation process of silicone rubber O-ring seals. Temperature is very important for the relaxation degree of silicone rubber O-ring seals. Regardless of the rubber material, it will accelerate its aging rate at high temperatures. When the temperature in the environment is higher and the product deformation exceeds 40%, the silicone rubber O-ring will slowly lose its elasticity, leading to leakage. These sealing rings will experience initial stress during the installation of silicone rubber O-ring seals in equipment. They will remain dormant for a long time and gradually relax as the temperature decreases. In some cases, they may dissipate with a sharp drop in temperature. Even if the rubber material is resistant to low temperatures, the stress generated at 20 degrees Celsius will not exceed 25%. Therefore, when setting the initial stress for installing silicone rubber O-ring seals, the factor of working environment temperature should be fully considered. 3.Compared with the above two factors, the influence of medium working pressure on the deformation of silicone rubber O-ring is greater. This is the most common situation that causes deformation of silicone rubber O-ring under various working conditions. With the development of hydraulic equipment, the pressure of hydraulic medium increases. Long term operation of silicone rubber O-ring in this high-pressure environment will lead to irreversible deformation. In this high-pressure environment, the deformation of rubber material will increase with the increase of temperature. The working fluid pressure is an important factor causing permanent deformation of silicone rubber O-ring seals. Therefore, suitable pressure resistant rubber materials should be selected according to the working pressure during design. The greater the homework pressure, the higher the hardness and high pressure resistance of the materials used.

Silicone waterproof sealing ring, as an excellent waterproof and sealing material, has a wide range of application prospects in industry and daily life. However, the length of its service life is directly related to the safety and reliability of the equipment, so it is widely used in the fields of cup lids, pot lids, and other daily necessities. As consumers, how can we ensure the service life of the silicone waterproof sealing ring when using it. Firstly, in terms of material selection, we need to have a certain judgment and understanding of the silicone water cup sealing ring, such as whether its material belongs to ordinary rubber or food grade silicone, and whether the product's softness and hardness are too soft, brittle, or hard.Secondly, regarding its size, the outer diameter of the silicone sealing ring for water bottles is usually slightly larger than the inner diameter to ensure that the sealing ring can be securely installed on the water bottle. The selection of thickness needs to be determined based on the material of the sealing ring, the usage environment, and the sealing requirements. Generally speaking, thicker sealing rings have better sealing performance and durability, but they can also increase the difficulty of installation and disassembly. And in terms of usage, we need to pay more attention to the details of the following aspects!1. The impact of usage environment: The temperature, humidity, pressure, and exposure to corrosive substances in the environment where silicone waterproof sealing rings are located will directly affect their service life.2. Temperature control: The optimal storage temperature for silicone seals is generally between -20 ℃ and+70 ℃. Although silicone has good high temperature resistance and can maintain stability in the temperature range of -60 ° C to+250 ° C, prolonged exposure to high temperatures can still accelerate its aging process. Therefore, it is necessary to avoid exposing the sealing ring to extreme high or low temperature environments to prevent physical changes in its material that may affect its sealing performance. 3. Humidity management: Excessive humidity can accelerate the aging process of silicone gel. Therefore, the storage environment should be kept relatively dry, and desiccants or humidity control devices can be used to control the environmental humidity and ensure that the silicone sealing ring is in suitable storage conditions.4. Light protection, ultraviolet radiation is one of the important factors affecting the aging of silicone gel. Silicone sealing rings should be stored in a dark and cool place, away from direct sunlight, to reduce damage from ultraviolet rays. 5. Although silicone has excellent chemical stability and corrosion resistance, it is still necessary to avoid direct contact with corrosive substances such as strong acids and bases to prevent chemical reactions that may cause damage.6. Frequent opening and closing actions or improper installation methods can cause physical damage to silicone waterproof seals and shorten their service life. Therefore, proper usage and maintenance methods are crucial.7. Reasonable installation: When installing silicone sealing rings, follow the product manual or professional guidance to ensure that the sealing rings are installed in place and avoid poor sealing or damage caused by being too tight or too loose. At the same time, attention should be paid to the direction of the sealing ring. Typically, silicone sealing rings have a flat surface and a protruding annular lip. When installing, it is necessary to ensure that the protruding lip faces the side of the sealing medium to achieve good sealing effect.

The required temperature for silicone buttons is generally controlled between -15 ℃ and+80 ℃, and the storage temperature should also be between -30 ℃ and+85 ℃. The storage time should also be one week. In addition, if the button is not pressed, it needs to be placed flat for long-term storage, but it can only be stored for about a month under compression. The humidity in the working environment should also be maintained between 45% and 95%, the working pressure should be between 86 and 106Kpa, and the contact rebound rate should be less than 12 milliseconds. The insulation resistance of silicone buttons needs to be greater than 1012 ohms/500VDC, and its breakdown voltage is usually greater than 25KV/mm. In addition, from the appearance, we can find that silicone products should be a delicate and uniform paste or present a viscous liquid. The drying time is generally within 10-30 minutes.

We can see that the patterns on silicone screen printing are very beautiful, so there must be someone interested in the process of silicone screen printing. Therefore, the editor will provide a detailed introduction to the silicone screen printing process. Screen printing is the earliest printing method. Screen printing is the abbreviation for "screen printing". Because screen printing requires a mesh board, it is also called screen printing. Generally, silk screen printing ink is thicker and brighter, and the printed patterns have a three-dimensional effect. Screen printing can also print finer lines and is suitable for large-area printing. Screen printing is the process of stretching silk fabrics, synthetic fiber fabrics, or metal wire mesh onto a frame, and using manual coating or photochemical plate making methods to produce screen printing plates. Modern screen printing technology uses photosensitive materials to produce screen printing plates through photographic plate making methods. Screen printing is the process of transferring ink through the mesh holes of graphics and text onto a substrate, forming an image that is identical to the original image. Silk screen silicone is a special type of silicone that is printed through screen printing. Recommendation: Silicone silk screen buttons Now let's talk about how many times do silk screen silicone need to be printed?Silk screen silicone is divided into manual printing and machine printing. Manual printing requires multiple prints to form, but the printing is too slow and the production capacity is not high. Because it is manually scraped, some patterns may have slight ghosting if not careful. Screen printing can only print one color at a time. If color matching is required, first print the first color, then dry it, adjust the position of the screen plate, and then print the second color. And machine printing only takes one time to form. Silk screen silicone has the characteristics of environmental protection, non delamination of printing colors, multiple printing effects, good adhesion, delicate hand feel, excellent performance, non-toxic and harmless. After screen printing, the three-dimensional effect of the product will be enhanced and become more beautiful. Mainly because silk screen silicone is non-toxic and harmless, there is no need to worry about safety issues.

Adhesive foot pads are widely used in various industries as a cushioning effect on product bases. They belong to a type of micro auxiliary accessory with low cost and simple function. However, some products may appear too redundant with them, and some items may not work without them. Therefore, with their functions and functions, many items currently need to use them for cushioning purposes. The difference lies in their different processes and structures. The function of the adhesive foot pad is based on the flat surface that fits the bottom as a whole. Currently, the common adhesive pads are made of flat surface with anti slip texture, and their main processes are the overall rolling process of the flat pad or the molding of the sheet material.This silicone gasket has a wide range of applications and is used in many seats, wardrobes, and electronic products. Therefore, under the premise of flat effect, both sides belong to a flat structure and can be used for adhesive bonding on various flat products. Another type is structural adhesive pads, which must be produced and processed using hydraulic molding technology to create concave convex and curved structures for bonding. This method is mainly used for processing irregular adhesive parts and can be used for customized adhesive parts processing in various fields. Both flat and irregular adhesive parts need to be bonded together, and the adhesive methods are divided into single-sided adhesive and double-sided adhesive. Secondly, adhesive paper is also very important. Currently, commonly used silicone adhesive paper is divided into TPE adhesive paper and double-sided adhesive paper.Adhesive backing paper is also divided into genuine and imitation products, with high strength and conventional viscosity. Different qualities are used in different products. Currently, 3M adhesive backing paper is commonly used for silicone foot pads, so its adhesive paper adhesion and strength should be considered in different foot pad lifetimes.

What is the function of silicone gloves? Silicone gloves are protective equipment made from food grade silicone, and have become an indispensable practical tool in modern kitchens due to their high temperature resistance, anti slip, and easy cleaning properties. From baking trays to hot pot frying, from cleaning utensils to handling frozen ingredients, silicone gloves provide comprehensive safety protection for chefs through physical protection and functional design. Its application scenarios cover home kitchens, baking studios, and the catering industry, becoming a key equipment for improving cooking efficiency and safety. 1. Core function: High temperature resistance and thermal insulation protectionThe core advantage of silicone gloves lies in their excellent high-temperature resistance. High quality silicone material can withstand extreme temperatures ranging from -40 ℃ to 250 ℃, effectively blocking heat transfer and preventing hand burns whether removing a 200 ℃ baking tray from the oven or handling a freshly cooked hot soup pot. Some products are further enhanced in insulation effect through thickened design or double-layer silicone structure, ensuring safety during long-term operation. For example, in baking scenarios, silicone gloves can safely lift high-temperature cake molds, avoiding the risk of burns caused by direct contact with metal molds. 2. Anti slip design and operational stabilityIn kitchen operations, oil and water stains often cause tableware to slip off, and silicone gloves solve this problem through surface texture design. The surface of the gloves adopts honeycomb shaped protrusions or wavy patterns to increase friction, even if the hands are stained with oil or water, they can still firmly grip heavy objects such as hot pots and soup bowls. This anti slip performance is particularly important in scenarios such as stir frying and holding hot soup, which can significantly reduce the risk of burns or breakage caused by slipping. In addition, some products are designed with finger and finger styles for different operational needs: finger styles have high flexibility and are suitable for fine operation; The connected finger style has strong wrapping ability and is suitable for grasping large appliances. 3. Easy to clean and hygienic safetyThe non oleophilic properties of silicone material give it the advantage of "self-cleaning". Oil stains and food residues are difficult to adhere to the surface of gloves. After use, simply rinse with water or mix with a small amount of neutral detergent to quickly restore cleanliness. This feature not only simplifies the cleaning process, but also avoids the problem of bacterial growth caused by oil and water absorption in traditional cotton gloves. For cooking scenarios that require frequent contact with raw meat, the ease of cleaning of silicone gloves can effectively reduce the risk of cross contamination. In addition, food grade silicone material has passed international safety certification, is non-toxic and odorless, and will not release harmful substances even when heated at high temperatures, ensuring safety in contact with food. 4. Multi functional scene adaptabilityThe application scenarios of silicone gloves far exceed basic protection requirements, and their versatility is reflected in the following aspects:Low temperature protection: When handling frozen ingredients, silicone gloves can isolate low temperatures, avoid hand frostbite, and maintain operational flexibility.Cleaning assistance: When used with cleaning agents, silicone gloves can protect the skin of the hands from chemical irritation, and their non slip surface can also improve wiping efficiency.Children's cooking assistance: Thick silicone gloves can provide safety protection for children, reduce the risk of burns during cooking, and cultivate hands-on skills.Outdoor Barbecue: In outdoor barbecue scenes, silicone gloves can resist the high temperature of charcoal fire and meet the anti slip requirements of open environments.Some products have further expanded their functional boundaries through innovative design, such as integrating magnetic hooks for easy storage, or adopting detachable finger cots to meet different operational needs.

How to check the quality of silicone products? Due to their unique physical and chemical properties, silicone products are widely used in various fields such as medical, maternal and child care, kitchen, electronics, and industry. However, the quality of silicone products in the market varies greatly, and how to scientifically check their quality has become a focus of consumer attention. This article will systematically analyze the quality inspection methods of silicone products from four dimensions: appearance, physical properties, chemical safety, and adaptability to usage scenarios, combined with industry testing standards and daily practical skills. 1. Appearance inspection: intuitive judgment of basic qualityAppearance is the first threshold for the quality of silicone products. The surface of high-quality silicone products should be smooth and flat, without defects such as bubbles, cracks, missing glue, impurities, etc. For example, food grade silicone tableware needs to be visually inspected for uniform color and clear and firm printing patterns to avoid health risks caused by pigment migration.In the medical field, the appearance inspection of silicone sealing rings is more stringent. It is necessary to use a magnifying glass or microscope to inspect the surface for burrs and burrs, as these small defects may affect the sealing performance and cause liquid or gas leakage. In addition, the dimensional accuracy of silicone products also needs to be measured using tools such as calipers and micrometers to ensure that the error with the design requirements is within the allowable range.2. Physical performance testing: quantitative evaluation of core indicatorsThe physical properties of silicone directly determine its applicable scenarios and service life.Hardness testing: Measure the hardness value (Shore A) of silicone gel using a Shore hardness tester, with different hardness ranges corresponding to different applications. For example, kitchen silicone shovels need to be soft and heat-resistant (with a hardness of about 30-40A), while sealing rings need to have a higher hardness (50-70A) to ensure sealing.Tensile and tear strength: The tensile strength of high-quality silicone should be ≥ 8MPa, and the tear strength should be ≥ 25kN/m. The tear resistance can be tested by stretching the sample to twice its original length, observing whether it quickly rebounds without deformation, or simulating the shear force in actual use.Temperature resistance: The temperature range of silicone is usually -40 ℃ to 230 ℃. You can observe its flexibility by boiling it in boiling water for 30 minutes or freezing it for 24 hours. High quality silicone should be kept without deformation or brittleness.Wear resistance: For high-frequency usage scenarios (such as silicone phone cases), friction testing can be used to simulate daily wear and observe whether there are scratches or discoloration on the surface. 3. Chemical safety testing: strict control of health risksThe chemical safety of silicone products is of utmost importance in quality inspection, especially for food grade and medical grade products.Hazardous substance detection: Professional institutions need to be used to detect whether silicone contains harmful substances such as heavy metals (such as lead and cadmium), plasticizers (such as phthalates), bisphenol A (BPA), etc. For example, the VOC (volatile organic compound) content of food grade silicone should be less than 0.5% and certified by international organizations such as FDA and LFGB.Migration substance test: Soak silicone products in a specific solvent (such as simulated gastric acid solution) to detect the precipitation of harmful substances. This test is particularly important for products that come into direct contact with food, such as baby pacifiers and tableware.Odor and combustion test: High quality silicone has only a slight raw material odor and no pungent chemical odor. When burning, white smoke should be emitted, and the residue is white powder; If combustion produces black smoke or irritating odors, it may contain inferior additives. 4. Scene adaptation detection: precise matching of functional requirementsThe quality of silicone products needs to be comprehensively evaluated based on specific usage scenarios.Sealing performance: For products such as sealing rings and bottle caps, their sealing effect can be tested by water or air pressure testing. For example, install the silicone seal ring on the container and apply pressure to observe for any leakage.Anti slip performance: For silicone foot mats, anti slip pads and other products, their anti slip coefficient can be measured by sliding tests on different material surfaces (such as glass, wood).Biocompatibility: Medical grade silicone gel needs to undergo biocompatibility tests such as cell culture and skin irritation testing to ensure that it is non-toxic and harmless when in contact with the human body.Aging resistance: Simulate long-term outdoor use environment through ultraviolet aging test to observe whether silicone products change color, become brittle or have decreased performance. The quality inspection of silicone products needs to be comprehensively evaluated from four dimensions: appearance, physical properties, chemical safety, and suitability for use scenarios.

What are the performance indicators of silicone kitchenware? Have we ever been confused about the reliability of this flexible material when silicone kitchenware silently replaces stubborn yellowed wooden shovels and fragile plastic spoons in our homes? How does it face a scorching hot oil pot unscathed? Can oil stains be easily removed? What are the safety and durability of use? High temperature limit performance: a calm response to kitchen heatThe high temperature challenge is the "lifeline" for testing kitchen utensils. Professional kitchen experiment data shows that high-quality food grade silicone kitchenware can easily withstand extreme temperature differences of -40 ℃ to 230 ℃. In the specific experiment, the silicone spatula was stirred continuously in hot oil at 230 ℃ for 15 minutes, and its shape remained intact; The other group of samples was frozen at -20 ℃ and immediately placed in a 200 ℃ environment, and the material did not undergo any fracture deformation. In contrast, conventional plastic kitchen utensils soften or even decompose significantly above 100 ℃, while wooden kitchen utensils will slowly carbonize and produce odors under repeated dry burning contact.This excellent high temperature resistance is endowed by the Si-O bond of silicone molecules, which has a binding energy of up to 444 kJ/mol, far exceeding the carbon carbon bond in ordinary plastics (348 kJ/mol), allowing silicone molecules to maintain strong structural stability even in extreme thermal environments. As representatives of high safety standards, the FDA and LFGB certifications in the United States and the European Union also clearly state that silicone can be used continuously at temperatures above 200 ℃ under manufacturing conditions that comply with the standards, and harmless migration occurs. Cleanliness advantage: Surface characteristics where stains cannot settleThe anti fouling ability of silicone gel is also impressive. Taking the experiment as an example, the cleaning convenience of commonly used silicone scrapers was tested after dipping them in coffee, soy sauce, and chili oil. The results showed that in the vast majority of cases, only rinsing with water was needed to restore their original appearance without the need for cleaning agents. Compared with wooden or bamboo kitchen utensils that are prone to staining and staining in daily life, silicone has a smooth and dense surface, eliminating the hidden dangers of microbial growth in crevices. Fearless of Time: The Endurance Legend of Silicone KitchenwareHigh quality silicone kitchenware exhibits strong tear resistance and wear resistance for daily use, with an expected lifespan of typically 8-10 years. In the specific experiment, after simulating the daily action of flipping food and continuously using weights to apply pressure and scrape, the surface of the silicone tool only showed tiny traces of use. In contrast, plastic products will gradually become brittle, crack, and release micro chips after years of use; Wood and bamboo materials are prone to cracking, deformation, and even mold growth during repeated wetting and drying, with an average service life of only about 2-3 years. Health cornerstone: safety and purity of food grade silicone gelThe safety of food grade silicone is closely related to its high purity. As the gold standard for safety, platinum silicone (usually distinguished by its white or semi transparent appearance) is made from high-purity raw materials that have been certified to be free of any harmful plasticizers. Consumers should clearly identify authoritative safety labels such as FDA and LFGB, which are important defense lines to avoid health risks caused by unqualified silicone products.

In modern industrial products, many basic things cannot be separated from the processing of molds. Many materials we see in daily life, such as hardware, plastic, silicone, and other punching materials, are made using different molds. Therefore, compared to many industry professionals, the importance of molds should be known. Similarly, in the silicone industry, it is no exception. Without molds and auxiliary tools, it is impossible to complete many of our products. In the silicone product industry, molds are the key to the entire product, and all products must be produced using molds to meet the requirements. However, silicone is different from plastic and hardware grinding tools in that it can be molded for sample making, which makes many people puzzled whether to use 3D printing or directly use production molds for sampling. Today, we will explain the different processes and methods of molds. Due to the fact that silicone product materials belong to soft colloids and are not processed using hard adhesives, 3D printing is a drawback. However, with the maturity of 3D printing, the use of soft adhesives is gradually becoming more mature. However, the material and workmanship of 3D printed soft adhesives still cannot achieve the desired effect and texture of the finished product. While the structure alone is not a problem, the effect still needs to be evaluated through the production of molds and the processing of finished products. The bulk mold and sample mold are the processes we need to go through. Many customers' silicone accessories cannot meet the requirements in terms of assembly and appearance, and they dare not rashly open production bulk molds. Otherwise, they are worried that the structure of the mold will not be correct after opening, and the appearance effect will not meet the requirements, resulting in poor quality of the silicone product and difficult project progress. Therefore, in the early stage of production, in order to meet the customer's appearance and structure requirements and achieve a similar fitting effect, we need to open a small mold and create a sample mold for comparison. After achieving the desired effect, we can proceed with the production of bulk molds. The difference between the production mold and the large goods mold is that the large goods mold can produce many points in a the first mock examination, which can be more efficient in production and processing in mass production. The sample mold is used for the qualification requirements of experimental samples in the early stage. Their difference is that one is only used for sample making experiments, and the other is used for mass production of large goods. So many friends do not understand why it is not possible to directly use sample molds for mold production. Today, I will explain to you that the production efficiency of silicone product processing manufacturers determines the unit price and profit of products. For example, a mold with one output can only produce 100 pieces per day, while a mold with 10 output can produce 1000 pieces per day. In the case of a large difference in production capacity, the processing cost of products will invisibly increase. Therefore, why silicone manufacturers are unwilling to use sample molds for mass production is also due to the increase in cost caused by different molds.
