Liquid silicone, also known as liquid silicone, is a liquid rubber that has good fluidity, fast vulcanization, and is safer and more environmentally friendly compared to solid high-temperature vulcanized silicone rubber. It can fully meet the requirements of food grade. Liquid silica gel has excellent tear resistance, resilience, yellowing resistance, thermal stability, heat resistance and aging resistance. Mainly used for infant and toddler products, medical supplies, and electronic products (buttons).
Liquid silicone is safer and more environmentally friendly, and can fully meet food grade requirements. According to the position of functional groups (i.e. crosslinking points) in the molecular structure, liquid rubbers with functional groups are often divided into two categories: one is called telechelic liquid rubbers where functional groups are located at both ends of the molecular structure; Another type is the random distribution of active functional groups in the main chain, which is called non telechelic liquid rubber. Of course, there are also those with both intermediate and terminal functional groups, and the current focus is on studying telechelic liquid rubbers. For liquid rubber, chain extenders or crosslinking agents with appropriate functional groups should be selected based on the active functional groups they contain.
purpose
Liquid silicone rubber can be used for trademarks, products, pacifiers, medical supplies, coatings, impregnation, and infusion. Used for molding molds, injection molding processes, cake molds, and other silicone products such as crystal glue, polyurethane, epoxy resin, etc. It is widely used in the electronic industry as a moisture-proof, shipping, insulation coating and sealing material for electronic components, providing dust-proof, moisture-proof, shockproof, and insulation protection for electronic components and assemblies. If transparent gel is used to encapsulate electronic components, it can not only play the role of shockproof and waterproof protection, but also can see the components and use the probe to detect the failure of the components and replace them. Damaged silicon gel can be filled and repaired again. It can also be used to manufacture product molding molds for materials such as gypsum, wax, epoxy resin, polyester resin, polyurethane resin, and low melting point alloys. It is applied in high-frequency embossing of artificial leather, shoe surface and sole shaping, manufacturing of arts and crafts, replication of ceramics, toy industry, furniture, household electronic components industry, as well as molding of gypsum and cement materials, wax products, models, and materials.
Product features
Liquid silicone has excellent transparency, tear resistance, resilience, yellowing resistance, thermal stability, water resistance, good breathability, heat aging resistance, and weather resistance. At the same time, its viscosity is moderate and easy to operate. The product has high transparency, and defects such as bubbles can be seen in the casting material inside the mold. The linear shrinkage rate is ≤ 0.1%, and the replicated product size is precise. The fundamental reason for liquid silicone vulcanization is that silicone requires processing and molding. The original silicone is an unformed material that is processed through vulcanization to produce the desired silicone product; There are many types of vulcanization molding, including machine high-temperature vulcanization molding. This type of silicone belongs to solid silicone, which is vulcanized and formed through vulcanizing agents and high-temperature equipment; Another type of machine operated molding is injection molding. This product is mixed with two types of liquid silicone through machine operation, injected into a mold, and then rapidly formed through high temperature.
