Organic silicon material according to the different forms can be divided into: silane coupling agent (silicone chemical reagents), silicone oil (silicone grease, silicone emulsions, silicone surface active agent), high temperature vulcanized silicone rubber, liquid silicone rubber, silicone resin composite goods. 

silicone rubber

silicone rubber is a straight chain of high molecular weight polysiloxane, molecular weight of 15 million or more generally, its structure is similar to the form and silicone oil. According to the silicon atoms on the different organic groups linked silicone rubber with dimethyl silicone rubber, methyl vinyl silicone rubber, methyl phenyl silicone rubber, fluorosilicone rubber, nitrile rubber, ethyl phenyl silicone rubber B support silicone rubber and many other varieties. According to their curing methods, can be divided into high-temperature vulcanized silicone rubber (HTV) and room temperature vulcanized silicone rubber (including low-temperature vulcanizing) silicone rubber two categories. No matter what type of silicone rubber, curing exothermic when the phenomena do not occur. Silicone Rubber is a high molecular weight polysiloxane (molecular weight is normally 40 to 80 million), room temperature vulcanized silicone rubber generally low molecular weight (3 to 6 million), the molecular chain ends (and sometimes also the middle of) the band one or two functional groups, under certain conditions (water or air in the appropriate catalyst), these functional groups can react to form high molecular weight cross-linked structure. RTV silicone rubber can be divided according to their curing mechanism of condensation forming type and processing; its packaging can be divided into Two-component and one component of two types. Constitute the main chain of silicone rubber silicon oxygen bond nature of the silicone rubber with natural rubber and other advantages not available, it has the widest operating temperature range (-100 ~ 350 ° C), resistance to high and low temperature performance, In addition, it also has excellent thermal stability, electrical insulation, weather resistance, ozone resistance, air permeability, high transparency, tear strength, excellent heat resistance and excellent adhesion, mobility, and mold release , some special silicone rubber also has excellent oil resistance, solvent resistance, high radiation and low temperatures in use and other characteristics. In the temperature range, silicone rubber can not only maintain a certain flexibility, elasticity and surface hardness, and no significant changes in mechanical properties, and resistance to prolonged thermal aging. As a special performance of silicone rubber, can be used for molding high-voltage edge of child and other electronic components, plastic has excellent resistance to tracking, excellent mold release; for the production of television sets, computers, photocopiers, etc., with good cooling and insulation. It is also used for weatherability and durability requirements of forming gaskets, packaging materials, electronic parts, auto electric parts of the protected material. Silicone rubber can be used for housing construction and repair, joint sealing and reservoir highways, bridges the caulking seal. Silicone rubber can also be used for adhesion, weathering resistance, alkali resistance, water resistance coating. As the silicone rubber high temperature, the amount of production of auto parts great. In addition, special-purpose silicone rubber, such as conductive silicone rubber, silicone rubber, foam rubber, molding silicon rubber, heat shrink silicone rubber and so on.
