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 baby 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 rubber with functional groups is often divided into two categories: one is called remote claw type liquid rubber, which has functional groups at both ends of the molecular structure; Another type is the random distribution of active functional groups in the main chain, which refers to the presence of functional groups within the molecular structure, known as non telechelic liquid rubber. Of course, there are also those with both intermediate functional groups and end functional groups, and the current focus is on the research of remote claw type liquid rubber. For liquid rubber, chain extenders or crosslinkers 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, coating, impregnation, and infusion. Silicone products used for molding molds, injection molding processes, cake molds, etc. for crystal glue, polyurethane, epoxy resin, etc. are widely used in the electronics industry as moisture-proof, transportation, insulation coating and sealing materials 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 to high-frequency embossing of artificial leather, surface and bottom modeling of shoes, manufacturing of arts and crafts, replication in the ceramics, toy industry, furniture, household electronic components industry, as well as the molding of gypsum and cement materials, wax products, model manufacturing, material molding, etc.

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 transparency of the product is high, and it can be seen whether there are defects such as bubbles in the casting material inside the mold. The linear shrinkage rate is ≤ 0.1%, and the size of the replicated product is precise. The fundamental reason for the vulcanization of liquid silicone is that silicone needs to be processed and molded. The original silicone is an unformed material that is made into the required silicone products through vulcanization process; 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 operation for molding is injection molding. This product is mixed with two types of liquid silicone through machine operation, injected into a mold, and then rapidly molded at high temperature.
