Dimethyl silicone rubber is the earliest silicone rubber put into commercial production. It can maintain good elasticity in the range of -60-200°C, has good aging resistance, excellent electrical insulation performance, moisture resistance, shock resistance and physiological inertia, etc. characteristic. Dimethyl silicone rubber is mainly used for fabric coating, and can also be made into various extruded and calendered products for electromechanical, aviation, automobile and medical industries. However, due to the low vulcanization activity of dimethyl silicone rubber, when it is used to manufacture thick products, it is difficult to vulcanize, the inner layer is easy to foam, and the high-temperature compression permanent deformation is large, so it has been replaced by methyl vinyl silicone rubber.
