Addition silicone rubber is usually composed of vinyl terminated polyphenylsiloxane, low molecular weight silicone oil, silicone resin, platinum catalyst, etc. According to the different application requirements of silicone rubber, appropriate fillers, additives and inhibitors can also be added. Silicone has a wide range of applications. Since its inception, its applications have spread across electronics, electrical appliances, aviation, aerospace, medical, machinery manufacturing, food molds and other industries.

Addition 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, dipping, coating, etc.

The requirements for silicone materials in aerospace applications are more stringent than in general applications. The addition type silicone rubber, which can be vulcanized at room temperature and under heating conditions, has been widely used in recent years due to its excellent electrical insulation, high and low temperature resistance, good thermal stability, ozone resistance and radiation resistance. Seals and putties for aerospace applications. The biggest feature of silicone rubber is low thermal vacuum weight loss. As an ideal space and polymer material, its bonding strength between metal and polyimide can reach 2Mpa.

Addition silicone rubber does not produce any by-products in the process of vulcanization, and has the characteristics of short curing time, low linear shrinkage, non-toxic, odorless, physiologically inert, and stable fungicides. Therefore, addition silicone rubber is also widely used in the medical industry, such as dental impression materials, soft pads for denture bases, prostheses, medical tubes, cosmetics, etc. Compared with the addition type silicone rubber, the condensation type silicone rubber has better water absorption, hydrophilicity and permeability resistance, so the condensation type silicone rubber is the most suitable denture soft pad material. In addition, addition silicone rubber is also involved in medical catheters. Medical silicone rubber catheters are the fastest growing and most widely used silicone rubber products. Addition silicone rubber is mainly used where it comes into contact with blood or needs to be embedded in the body.
