Raw rubber is the abbreviation of methyl vinyl silicone rubber, which is copolymerized by dimethyl siloxane and a small amount of vinyl siloxane. It has excellent fluidity and is the basic raw material for producing and mixing silicone rubber. The vinyl content of commonly used methyl vinyl silicone rubber is generally 0.04, 0.08, 0.16, 0.24, etc., and different vinyl content materials are used according to the different properties of the mixing silicone rubber. to be produced.

After adding reinforcing fillers (precipitated/fumed silica) and additives, the raw rubber can be cross-linked at high temperature to form an elastomer, which can be used to manufacture various types of compound such as molding rubber, extrusion rubber, electrical insulating rubber, and flame retardant rubber.
