What is the composition of silicone rubber?
The chemical composition of silicone rubber is silicon-oxygen. Silicone rubber refers to a rubber that is composed of silicon and oxygen atoms in the main chain. Two organic groups are usually attached to the silicon atom. Ordinary silicone rubber is mainly composed of methyl and a small amount of ethylene. The introduction of phenyl groups can improve the high and low temperature resistance of silicone rubber, and the introduction of trifluoropropyl and cyano groups can improve the temperature and oil resistance of silicone rubber.

Silicone rubber has excellent low-temperature resistance, and it can generally work at -55°C. After the introduction of phenyl, the temperature can reach -73℃. Silicone rubber also has outstanding heat resistance. It can be operated for a long time at 180°C, and can withstand a few weeks or longer when it is slightly higher than 200°C, and it can withstand high temperatures above 300°C instantaneously.
