Appearance Color: High quality food grade silicone products have pure and uniform colors, without obvious color differences or impurities. If the color is uneven or there are abnormal color spots, it may indicate that the silicone raw material is impure or impurities have been mixed in during the production process. Surface: The surface should be smooth and free of obvious defects such as bubbles, cracks, scratches, etc. Bubbles can affect the strength and sealing of products, cracks may be caused by poor raw material quality or improper molding processes, and scratches may affect the normal use and appearance of products. Transparency: If it is a transparent food grade silicone product, its transparency should be high, and the internal structure of the product can be clearly seen. Poor transparency may be due to excessive fillers or other impurities added to the silicone gel. Physical property Hardness: The hardness of food grade silicone products should be moderate, generally between Shore A30-70 degrees. The hardness of a product can be roughly judged by pressing its surface. High quality products should have a certain degree of elasticity and be able to quickly return to their original state after pressing. If it is too hard, it may affect the comfort and sealing during use; If it is too soft, it may cause the product to deform and break easily during use. Tensile strength and elongation at break: High quality food grade silicone products should have high tensile strength and elongation at break, indicating their good toughness and tensile resistance.

What is the function of vulcanization treatment for silicone rubber products? In high-temperature workshops, uncured silicone is like soft rubber putty, while vulcanized products can withstand temperatures of thousands of degrees Celsius. This transformation from liquid to solid is the soul of silicone industrial applications. As the core process for optimizing the performance of organic silicon materials, vulcanization treatment reconstructs molecular chain cross-linking, endowing the material with key characteristics such as high temperature resistance, tear resistance, and aging resistance.   1.The structural revolution at the molecular level   The essence of vulcanization treatment is the process of establishing a three-dimensional network structure. Taking the sulfur vulcanization system as an example, crosslinking agents undergo condensation reactions with hydroxyl groups in silicone rubber, forming 3-5 crosslinking points per gram of silicone gel, resulting in a significant increase in tensile strength from 1.5 MPa to 8 MPa. In the medical field, platinum catalyzed addition crosslinked silicone catheters have a fracture elongation of up to 400%, far exceeding traditional process products. Even more ingenious is the dynamic vulcanization technology, where TPV (SBS/SEBS) materials achieve multiple recycling through reversible cross-linking, solving the problem of difficult degradation of thermoplastic elastomers.   The crosslinking density directly affects the material properties. When the distance between crosslinking points is shortened from 5nm to 2nm, the fatigue life of silicone increases by three times, which is the key reason why automotive engine seals use high crosslinking density silicone. In electronic component packaging, nanoscale cross-linked structures can stabilize the dielectric constant below 2.8, ensuring signal integrity of 5G communication devices in environments ranging from -55 ℃ to 200 ℃.   2.Directional regulation of functional characteristics   Different vulcanization systems give rise to differentiated performance. The sulfur vulcanization system endows the material with high elasticity and is suitable for flexible components such as buttons and sealing rings; Peroxide vulcanization improves heat resistance, allowing car lampshades to work for a long time at 200 ℃; The sulfur free crosslinking of platinum catalytic system has achieved biocompatibility (cytotoxicity ≤ 0.1) of implantable cardiac pacemaker silicone. In the field of photovoltaics, the refractive index of two-component vulcanized silicone can be adjusted within the range of 1.40-1.55, making it an ideal choice for efficient packaging materials.   Special craftsmanship creates unique value. The irradiation vulcanization technology enables molecular cross-linking of silicon film under electron beam irradiation, and this cold processing method is particularly suitable for precision optical lens manufacturing. The surface energy of silica gel after plasma treatment is increased to 72mN/m, achieving a coating adhesion level of 4B standard. A semiconductor company has achieved zero particle detachment in a wafer etching machine using plasma sulfurization treated sealing rings, resulting in an 18% increase in yield rate.   3.Breakthrough in performance of application scenarios   In extreme environments, vulcanized silicone exhibits extraordinary resistance. The spacecraft sealing ring needs to withstand a vacuum environment of -100 ℃ and a thermal cycle of 400 ℃. The fluorosilicone rubber that has undergone secondary vulcanization can maintain a compression permanent deformation of ≤ 15%. The phenyl silicone rubber used in deep-sea exploration equipment can maintain sealing performance at a depth of 11000 meters by enhancing its compressive strength through phenyl cross-linking. The actual measurement data of a deep-sea probe shows that its vulcanized silicone seal has worked continuously for 2000 hours without leakage in the simulated Mariana Trench environment.   Emerging fields give rise to innovative applications. Solid state batteries are coated with ceramic and silicone gel, and a gradient cross-linking layer is formed through in-situ vulcanization to reduce the interface impedance to 5 Ω· cm2. In 3D bioprinting, UV cured vulcanized silicone can achieve a layer thickness accuracy of 0.1mm, and the burst pressure of vascularized tissue scaffolds can reach 300mmHg. In the food industry, the total amount of migration of peroxide vulcanized silica gel is less than 0.5mg/kg, which fully complies with the EU/1935/2004 food contact material standard.   4.Green Technology and Future Evolution   Environmental pressure drives technological innovation. The sulfur free sulfurization system adopts radiation sulfurization or peroxide/radiation synergistic sulfurization to reduce VOC emissions by 90%. The industrialization of bio based vulcanized silicone has begun, and a certain enterprise has reduced the carbon footprint of its products by 42% by using plant-based silane coupling agents. A more cutting-edge approach is 4D printing of vulcanized silicone gel, which achieves adaptive deformation of implants triggered by body temperature through the cross-linking gradient design of shape memory polymers.   When the vulcanization process meets artificial intelligence, material development enters a new era. The machine learning model can shorten the formula development cycle from 3 months to 72 hours by analyzing 100000 sets of vulcanization parameters. The intelligent vulcanization system developed by a certain tire enterprise reduces the standard deviation of product consistency from 0.3 to 0.08 by monitoring the fluctuation of cross-linking density online. This digital upgrade not only improves efficiency, but also endows materials with dynamic adaptability - future vulcanized silicone may be able to autonomously adjust the cross-linking state according to the usage environment.

Silicone buttons include single point silicone buttons, remote control silicone buttons, conductive silicone buttons, mobile phone silicone buttons, light touch silicone buttons, transparent silicone buttons, keyboard buttons, password machine buttons, car buttons, film buttons, laser engraved buttons, reset buttons, home buttons, PC buttons, learning machine buttons, pose machine buttons, password machine buttons, digital product buttons, p+r buttons, etc.   In the production process of silicone buttons, especially when producing thinner buttons, the next step is to remove the edges, which sometimes makes it very easy to break. So what is the reason for this situation?   1. The temperature during molding is too high. Silicone buttons become brittle when the temperature is too high during molding, and are prone to cracking and defects after demolding. 2. The operation method during demolding is incorrect. When demolding, many mold makers have not received professional training or are not careful in their work. They do not follow strict operation instructions to demold, which can lead to the breakage of silicone buttons. 3. Incomplete vulcanization of silicone buttons. When the temperature of the silicone button molding mold is too low or the vulcanization time is too short, it will cause the product to adhere tightly to the mold and be difficult to demold. 4. The silicone material used is too poor. Some factories blindly reduce costs and use inferior silicone button raw materials, resulting in poor quality silicone buttons, poor rubber material, poor toughness, and memory rupture. 5. Poor release of silicone buttons during mold lifting can cause the product to break during the lifting process. 6. Mold cavities with rough surfaces or accumulated dirt are not conducive to demolding, and molds that are difficult to demold are prone to breakage.

Nowadays, the application of silicone products is very extensive in China, especially in kitchen supplies. Silicone kitchenware brings greater commercial and practical value. This is our continuous investment in research and development technology to develop lined silicone products, accelerate the development and progress of our own technology, and strengthen the development of high-performance and high use silicone products. Silicone kitchenware undoubtedly uses silicone as the raw material, and the main component of silicone is a natural ingredient that exists in sand, stone, and crystals. Silicone is like tempered glass that people usually see. It is non-toxic, colorless, odorless, and does not dissolve solvents other than water, strong alkali, and sulfuric acid. Its chemical properties are very stable, so silicone kitchenware is very environmentally friendly and zero polluting. Compared to other iron, stainless steel plates, and porcelain kitchen utensils, silicone kitchenware also has many beloved advantages. Silicone is a raw material for enzyme adsorption, which has high wear resistance, flexibility, corrosion resistance, temperature adaptability, and high temperature resistance. Therefore, it is not easy to produce difficulties such as rust, heat, and breakage during the entire process of use. In addition, silicone kitchenware also has high temperature adaptability, so it can be used in both hot and cold drinks in daily life. And it can also have the function of insulation and heat preservation in the cold winter, and in addition to insulation and heat preservation, it will not burn the hands of the user. People generally accept the use of silicone kitchenware, which is inevitable and a trend. Not only is silicone material so excellent, but also the benefits and convenience that silicone kitchenware brings to people's daily lives. The above is all about why silicone kitchenware is so popular.

Electronic device sealing: Silicone foam strips have good insulation and sealing properties, and can be used for sealing electronic devices such as mobile phones, tablets, computers, etc., to prevent dust and moisture from entering the interior of the device, protect electronic components from damage, and improve the reliability and stability of the device. Sealing of wires and cables: Silicone foam strips are used to seal the joints of wires and cables, which can prevent moisture and moisture from entering, avoid short circuits, leakage and other faults in wires and cables, and also play a buffering and shock-absorbing role, protecting wires and cables from external damage. Electrical product buffering: In some electrical products, such as televisions, speakers, etc., silicone foam strips can be used for buffering and fixing between components, reducing vibration and noise, and improving the sound quality and stability of the product.

1. Color change Color darkening When silicone rubber products are exposed to high temperatures for a long time, the organic compounds inside may undergo oxidation reactions. These additives will generate some colored substances during the oxidation process, causing the color of silicone rubber to darken. For example, in some industrial production environments, silicone rubber products used for sealing high-temperature equipment may gradually turn from white to light yellow or brown after several months of use. Ultraviolet radiation is also an important factor in causing discoloration of silicone rubber. The energy of ultraviolet radiation can cause certain chemical bonds in the molecular chain of silicone rubber to break, generating free radicals. These free radicals further trigger a series of chemical reactions, producing conjugated colored substances. Like some outdoor silicone rubber sealing strips, long-term exposure to sunlight will gradually darken the surface color, from light to dark. Yellow color This is mainly due to the chemical changes that occur during the aging process of additives in silicone rubber, such as certain organic silicone oils or silicone resins. These additives may undergo yellowing reactions, causing the entire silicone rubber product to appear yellowed. For example, some silicone rubber gaskets used in electronic devices may turn yellow during long-term operation due to the combined effects of internal heat and external light.   2. Fading If dyes and other coloring agents are added to silicone rubber products, these coloring agents may gradually decompose or be lost during the aging process. For example, some colored silicone rubber toys may gradually become dull and even show obvious fading after prolonged use and sun exposure. This is because the dye molecules in toys undergo changes in their chemical structure and color characteristics due to factors such as light and heat, ultimately leading to fading.

Can silicone products be used in high temperature or extreme environments? Silicone products are widely used in various industries such as medical, food, electronics, and automotive due to their excellent physical and chemical properties. However, many people have doubts about the performance of silicone products in high temperatures or extreme environments: can silicone products withstand high temperatures? Will it fail under extreme conditions?   High temperature resistance of silicone products Silicone is a polymer material, mainly composed of silicon dioxide. The high temperature resistance of silicone products mainly depends on their formula and manufacturing process. The following is the performance of silicone products in high temperature environments: Temperature resistance range The temperature resistance range of ordinary silicone products is generally -60 ℃ to 200 ℃. Specially formulated silicone products (such as high-temperature silicone) can withstand temperatures up to 300 ℃. Stability at high temperatures Silicone can still maintain its elasticity and mechanical properties at high temperatures, and is not easily deformed or melted. Silicone has good thermal stability and will not release harmful substances even when exposed to high temperatures for a long time. Application scenarios Silicone products are widely used in high-temperature environments, such as automotive engine seals, oven pads, hot water pipe seals, etc.   Performance of silicone products in extreme environments In addition to high temperatures, silicone products also perform well in other extreme environments: 1.

Silicone products can perform well in high temperature, low temperature, chemical corrosion, and high humidity environments.

1. Raw material preparation: laying the foundation for quality The main raw material for silicone products is silicone rubber, which is a high molecular weight elastomer with silicon oxygen bonds as the main chain. There are many types of silicone rubber, which can be divided into high-temperature vulcanized silicone rubber (HTV) and room temperature vulcanized silicone rubber (RTV) based on their vulcanization characteristics and performance. Different types of silicone rubber are suitable for different product manufacturing. For example, high-temperature vulcanized silicone rubber has high strength and heat resistance, and is commonly used to manufacture industrial products with high performance requirements; Room temperature vulcanized silicone rubber has the advantages of easy operation and adjustable curing speed, and is commonly used in sealing, potting, and other scenarios. In addition to the silicone rubber matrix, various additives need to be added to improve the performance of silicone products. Common additives include vulcanizing agents, reinforcing agents, plasticizers, pigments, etc. Vulcanizing agent is a key substance that causes cross-linking reaction and forms a three-dimensional network structure in silicone rubber. It determines the vulcanization speed and degree of silicone products. Reinforcing agents can improve the strength and hardness of silicone rubber, and commonly used reinforcing agents include white carbon black. Plasticizers are used to increase the flexibility and processability of silicone rubber, making the product easier to shape. Pigments endow silicone products with rich and colorful colors, meeting the aesthetic needs of different consumers. In the raw material preparation stage, it is necessary to accurately weigh the silicone rubber and various additives according to the formula ratio and mix them thoroughly and evenly. This process is usually carried out in professional mixing equipment, such as open mixers or internal mixers. Through mechanical stirring and shearing, various raw materials are fully dispersed to form a uniform adhesive material, preparing for subsequent molding processes.   2. Forming processing: endowing the product with a shape The uniform adhesive obtained through the raw material preparation stage is then processed into semi-finished products with specific shapes in the molding process. There are various molding methods for silicone products, including compression molding, injection molding, extrusion molding, and liquid silicone injection molding. molding Compression molding is one of the most commonly used methods for molding silicone products. It is suitable for manufacturing products with complex shapes and high dimensional accuracy requirements. During the molding process, the rubber material is first placed into the preheated mold cavity, and then a certain pressure is applied through a hydraulic press to fill the cavity with the rubber material under high temperature and pressure, and undergo vulcanization reaction. After a period of pressure holding and vulcanization, open the mold and take out the product. The advantages of compression molding are high dimensional accuracy and good surface quality of the product, but the production efficiency is relatively low, making it suitable for small batch and multi variety production. injection molding Injection molding is an efficient and automated molding method. It heats and plasticizes the rubber material through the screw of the injection machine, and injects it into the closed mold cavity for rapid vulcanization and molding under high temperature and pressure. Injection molding has the advantages of high production efficiency, stable product quality, and the ability to achieve automated production. It is suitable for mass production of silicone products with relatively simple shapes, such as silicone buttons and sealing rings. Extrusion Extrusion molding is mainly used to manufacture silicone products with fixed cross-sectional shape and continuous length, such as silicone tubes, silicone strips, etc. During the extrusion molding process, the rubber material is extruded into the desired shape through the die of the extruder under the action of the screw, and then undergoes vulcanization treatment to shape it. Extrusion molding has the advantages of high production efficiency and continuous production, which can meet the needs of large-scale production. Liquid silicone injection molding Liquid silicone injection molding is a new molding technology developed in recent years. It uses liquid silicone rubber as raw material, and precisely injects the liquid silicone rubber into the mold cavity through a dedicated liquid silicone injection machine, rapidly vulcanizing and forming at low temperatures. Liquid silicone injection molding has the advantages of fast molding speed, high product accuracy, and the ability to achieve complex structural molding, especially suitable for manufacturing silicone products in medical, food, and other fields that require high hygiene.   3. Sulfurization treatment: key to improving performance Sulfurization is a key step in the production process of silicone products, which determines the physical and chemical properties of silicone products. During the vulcanization process, the molecular chains of silicone rubber undergo cross-linking reactions under the action of vulcanizing agents, forming a three-dimensional network structure, thereby endowing silicone products with properties such as elasticity, strength, and heat resistance. The vulcanization method used in different molding methods also varies. Compression molding and injection molding usually use hot vulcanization method, which heats the mold to a certain temperature, causing the rubber material to undergo vulcanization reaction at high temperature. Liquid silicone injection molding often adopts low-temperature rapid vulcanization technology, which achieves rapid vulcanization at lower temperatures by adding special vulcanizing agents and catalysts, thereby shortening the production cycle and improving production efficiency. The vulcanization time and temperature are important factors affecting the vulcanization effect. Short vulcanization time and incomplete vulcanization reaction can affect the physical and chemical properties of the product; If the vulcanization time is too long, it will lead to over vulcanization of the product, resulting in problems such as decreased elasticity and brittleness. Excessive sulfurization temperature can cause defects such as bubbles and burning on the surface of the product; If the vulcanization temperature is too low, the vulcanization speed will be slow and the production efficiency will be low. Therefore, in the production process, it is necessary to accurately control the vulcanization time and temperature based on factors such as the type of silicone rubber, the shape and size of the product, etc., to ensure the quality of the product.   4. Post processing steps: Improve product details The semi-finished silicone products obtained after molding and vulcanization treatment require a series of post-processing steps to become the final product. Common post-processing procedures include trimming, cleaning, inspection, and packaging. Trimming During the molding process, due to factors such as the mold clamping line, there may be some excess adhesive residue at the edges of the product. The trimming process is to remove these excess adhesive edges, making the edges of the product smooth and neat. There are two methods for edge trimming: manual trimming and mechanical trimming. Artificial edge trimming is suitable for products with complex shapes and high precision requirements, but the production efficiency is low; Mechanical trimming is suitable for products with regular shapes and large batches, and has the advantages of high production efficiency and stable trimming quality. clean Silicone products may be contaminated with impurities such as oil and dust during the production process, and require cleaning treatment. The cleaning methods include water washing, solvent cleaning, etc. Water washing is a commonly used cleaning method with advantages such as low cost and environmental friendliness. However, for some products with heavy oil stains, solvent cleaning may be required. The cleaned products need to be dried to ensure their quality. test Inspection is an important step in ensuring the quality of silicone products. During the inspection process, it is necessary to conduct comprehensive testing on the appearance, size, physical properties, and chemical properties of the product. Appearance inspection mainly checks whether there are defects such as bubbles, cracks, and missing materials on the surface of the product; Dimensional inspection uses measuring tools to check whether the dimensions of the product meet the design requirements; Physical performance testing includes testing of indicators such as hardness, tensile strength, tear strength, etc; Chemical performance testing mainly tests whether the product meets relevant environmental standards and hygiene requirements. Only products that have passed strict inspection and are qualified can proceed to the next process. package Packaging is the final process in the production of silicone products. Appropriate packaging not only protects products from damage during transportation and storage, but also enhances the product's image and market competitiveness. The selection of packaging materials should be determined based on the characteristics and usage requirements of the product. Common packaging materials include plastic bags, paper boxes, wooden boxes, etc. During the packaging process, it is also necessary to label the product name, specifications, model, production date, and other information on the packaging for consumers to identify and use.
