Silicone rubber has excellent elasticity, as well as excellent properties such as weather resistance and physiological inertness, and is widely used in fields such as aerospace, rail transit, electronics, biomedical, etc.

The widely used silicone rubber in China is vinyl silicone rubber developed in the 1960s, with main grades including 110-1, 110-2, and 110-3.

Introducing diphenyl siloxane or methylphenyl siloxane chains into the molecular chain of vinyl silicone rubber yields phenyl silicone rubber. The former is called diphenyl vinyl silicone rubber (abbreviated as diphenyl silicone rubber), which was identified and put into production in the 1990s and has grades 120-1 and 120-2; The latter is called methylphenyl vinyl silicone rubber (abbreviated as methylphenyl silicone rubber), and domestic products were developed a few years ago.

Introducing trifluoropropyl into the molecular chain of vinyl silicone rubber is called fluorosilicone rubber, which has better resistance to low temperature and oil.
