Liquid silicone rubber is safer and more environmentally friendly, and can fully meet food-grade requirements. According to the position of the functional groups (i.e., cross-linking points) contained in the molecular structure, liquid rubber with functional groups is often divided into two categories: one is called telechelic liquid rubber with functional groups at both ends of the molecular structure; the other is The active functional groups are randomly distributed in the main chain, that is, those with functional groups within the molecular structure are called non-telechelic liquid rubber. Of course, there are also those with both intermediate functional groups and terminal functional groups. The current focus is on research on telechelic liquid rubber. For liquid rubber, chain extenders or cross-linking agents with appropriate functional groups should be selected based on the reactive functional groups they contain.
use
Liquid silicone rubber can be used for trademarks, products, pacifiers, medical supplies, coating, dipping and perfusion, etc. It is used in molding molds for crystal glue, polyurethane, epoxy resin, etc., injection molding processes, cake molds and other silicone products. It is widely used in the electronics industry as moisture-proof, shipping, and insulating coating and potting materials for electronic components. , which protects electronic components and assemblies from dust, moisture, shock, and insulation. If transparent gel is used to encapsulate electronic components, it not only provides shockproof and waterproof protection, but also allows the components to be seen and probes can be used to detect component failures and replace them. The damaged silicone gel can be encapsulated again. repair. It can also be used to make molds for products made from materials such as gypsum, wax, epoxy resin, polyester resin, polyurethane resin, and low-melting point alloys. It can be used in high-frequency embossing of artificial leather, upper and sole modeling of shoes, and manufacturing of arts and crafts. Ceramics, toy industry, furniture, household appliances and electronic components industry reproduction, as well as the molding of plaster and cement materials, the molding of wax products, the manufacturing of models, the molding of materials, etc.
