Dimethyl silicone rubber is one of the earliest commercially produced silicone rubbers, which can maintain good elasticity in the range of -60 to 200 ℃, has good aging resistance, excellent electrical insulation performance, as well as moisture resistance, shock resistance, and physiological inertness.
Dimethyl silicone rubber is mainly used for strong material coating, and can also be made into various extruded and rolled products for industries such as electromechanical, aviation, automotive, and medical. However, due to the low vulcanization activity of dimethyl silicone rubber, it is difficult to cure when used to manufacture thick products, and the inner layer is prone to foaming and permanent deformation under high temperature compression. Therefore, it has been replaced by methyl vinyl silicone rubber.
