It is composed of addition type methyl vinyl silicone rubber, low molecular weight silicone oil, silicone resin, platinum catalyst, etc. According to the different application requirements of methyl vinyl silicone rubber, appropriate fillers, additives and inhibitors can also be added. The application of silicone is very wide. Since its advent, it has been used in electronics, electrical appliances, aviation, aerospace, medical, machinery manufacturing, food molds and other industries.
Addition type methyl vinyl silicone rubber has excellent dielectric properties, excellent low temperature resistance, weather resistance and good adhesion, and is widely used in electronics and electrical for sealing, bonding, impregnation, coating, etc.
The requirements for silicone materials in aerospace applications are more stringent than general applications. Addition type methyl vinyl silicone rubber, which can be vulcanized at room temperature and heating conditions, has been widely used in aerospace sealing and putty in recent years due to its excellent electrical insulation, high and low temperature resistance, good thermal stability, ozone resistance and radiation resistance. The biggest feature of silicone rubber is its low thermal vacuum weightlessness. As an ideal space and polymer material, its metal and polyimide bonding strength can reach 2Mpa.
Addition type methyl vinyl silicone rubber does not produce any by-products during the vulcanization process, and has the characteristics of short curing time, low linear shrinkage, non-toxic, odorless, physiological inertness, stable fungicide, etc. Therefore, addition type silicone rubber is also widely used in the medical industry, such as dental impression materials, denture base soft pads, prostheses, medical tubes, cosmetics, etc. Compared with addition type silicone rubber, condensation type methyl vinyl silicone rubber has better water absorption, hydrophilicity, and anti-permeability, so condensation type silicone rubber is the most suitable denture soft pad material. In addition, addition type methyl vinyl silicone rubber also involves medical catheters. Medical silicone rubber catheters are the fastest growing and most widely used silicone rubber products. Addition type silicone rubber is mainly used in places that come into contact with blood or need to be embedded in the body.
