Due to the introduction of a small amount of vinyl groups into the macromolecular structure of silicone rubber, the vulcanization processing performance of silicone rubber can be greatly improved. Therefore, most of the silicone rubber currently used contains vinyl groups. Methyl vinyl silicone rubber is the most commonly used type of silicone rubber and currently dominates the production of silicone rubber both domestically and internationally. Due to the introduction of partially unsaturated vinyl groups on its side chains, its processing and physical mechanical properties are superior to those of two base silicone rubbers. In addition to the general characteristics of dimethyl silicone rubber, it also has a wide range of operating temperatures and can maintain good elasticity in the range of 60-260 ℃. It is easier to cure than dimethyl silicone rubber, has smaller compression permanent deformation, better solvent expansion resistance, high pressure steam stability, and excellent cold resistance. Moreover, because it uses low activity peroxides for vulcanization, it reduces the weak points of gas bubbles and poor rubber stability during vulcanization. Therefore, methyl vinyl silicone rubber can generally be used to make thicker products. Methyl vinyl silicone rubber is the most widely used variety of silicone rubber. In recent years, various high-performance and special-purpose silicone rubbers have emerged, most of which are based on vinyl silicone rubber, such as high-strength silicone rubber, low compression permanent deformation silicone rubber, non post vulcanized silicone rubber, heat-resistant conductive silicone rubber, and medical silicone rubber. Methyl vinyl silicone rubber is widely used in the aviation industry as a gasket, sealing material, and protective layer for fragile and shock resistant components; In the electrical industry, it can be used as advanced insulation materials for electronic components, dynamic sealing rings for high-temperature potentiometers, and sealing rings for underground long-distance communication equipment; In medicine, methyl vinyl silicone rubber is used for surgical plastic surgery, artificial heart valves, blood vessels, etc. due to its low physiological response to the human body and non toxicity.
