It is composed of addition methyl vinyl silicone rubber, low molecular weight silicone oil, silicone resin, platinum catalyst, etc. According to different application requirements of methyl vinyl silicone rubber, appropriate fillers, additives and inhibitors can also be added. Organic silicon is widely used. Since its appearance, it has been widely used in electronics, electrical appliances, aviation, aerospace, medical, machinery manufacturing, food mold and other industries.

Additive methyl vinyl silicone rubber has excellent dielectric properties, excellent low temperature resistance, weather resistance and good adhesion. It is widely used in electronic and electrical fields for sealing, bonding, dipping, coating, etc.
The requirements for silicone materials in aerospace applications are stricter than those in general applications. The addition molded methyl vinyl silicone rubber, which can be vulcanized under room temperature and heating conditions, has been widely used in the field of aviation and aerospace in recent years due to its excellent electrical insulation, high and low temperature resistance, good thermal stability, ozone resistance and radiation resistance. The greatest feature of silicone rubber is its low thermal vacuum weight loss. As an ideal space and polymer material, its adhesion strength between metal and polyimide can reach 2Mpa.

The addition molded methyl vinyl silicone rubber does not produce any by-products in the sulfide process, and has the characteristics of short curing time, low linear shrinkage, non-toxic, tasteless, physiological inert, stable fungicide, etc. Therefore, addition silicone rubber is also widely used in the medical industry, such as dental impression materials, denture base soft pads, artificial limbs, medical tubes, cosmetics, etc. Compared with addition silicone rubber, condensation type methyl vinyl silicone rubber has better water absorption, hydrophilicity and impermeability, so condensation type silicone rubber is the most appropriate soft denture cushion material. In addition, the addition molding methyl vinyl silicone rubber also relates to medical catheters. Medical silicone rubber catheter is the fastest growing and most widely used silicone rubber product. The addition silicone rubber is mainly used in the places where it contacts blood or needs to be embedded in the body.
