Silicone rubber (English name: Silicone rubber) is divided into thermal vulcanization type (high temperature vulcanization silica gel HTV) and room temperature vulcanization type (RTV). Among them, the room temperature vulcanization type is divided into condensation reaction type and addition reaction type.

High temperature silicone rubber is mainly used to manufacture various silicone rubber products, while room temperature silicone rubber is mainly used as adhesive, potting material or mold. The thermal vulcanization type has the largest amount, and the thermal vulcanization type is divided into methyl silicone rubber (MQ), methyl vinyl silicone rubber (VMQ, the largest amount and product brand), methyl vinyl phenyl silicone rubber (PVMQ low temperature resistance, radiation resistance) , Others include eye silicone rubber, fluorosilicone rubber, etc.

Silicone resin, scientific name polysiloxane resin (English name: Silicone resin) is a polyorganosiloxane with a highly cross-linked network structure. It has the dual characteristics of organic resin and inorganic material. Silicone resin has unique physical and chemical properties.

Classification of silicone resin Silicone resin is a cross-linked semi-inorganic high polymer with a silicon-oxygen-silicon main chain and an organic group connected to the silicon atom. It has outstanding weather resistance with the direct production of silicone monomer silicone resin, which is beyond the reach of any organic resin. Even under strong ultraviolet radiation, silicone resin is resistant to yellowing.

Silicone resin adhesives and silicone adhesives can be divided into adhesives based on silicone resin and adhesives based on silicone rubber according to the source of raw materials. The former is mainly used for bonding metals and heat resistance. Such metals have good bonding performance, and are easy to bond to glass and ceramics, but have poor adhesion to copper. Silicone adhesive based on pure silicone resin.
