Methylvinyl silicone rubber, also known as VMQ rubber, is a polymer material with excellent heat resistance, cold resistance, oxidation resistance, chemical corrosion resistance and other excellent properties. It is mainly polymerized from methyl vinyl siloxane monomer and has a unique chemical structure, that is, methyl and vinyl groups are introduced into the siloxane chain.

Due to its special structure and chemical properties, methyl vinyl silicone rubber can maintain its physical and mechanical properties in a wide range of temperature and pressure. It can maintain elasticity at extremely low temperature and has good heat resistance at high temperature. In addition, methyl vinyl silicone rubber also has excellent oxidation resistance, radiation resistance, ozone resistance, acid and alkali resistance, chemical corrosion resistance and other properties, making it an important high-temperature sealing material, electrical insulation material, medical equipment material, auto parts material, etc.

However, methyl vinyl silicone rubber also has some disadvantages. For example, its mechanical strength is relatively low, and it is vulnerable to shear and tear. In addition, its water vapor permeability is also large, which is not suitable for some sealing applications with high requirements.
In a word, methyl vinyl silicone rubber is an excellent polymer material with broad application prospects. With the development of technology and the increase of application demand, it is believed that it will have a wider application space in the future.
