[0002] Silicone rubber refers to a rubber whose main chain is composed of alternating silicon and oxygen atoms, and the silicon atom is usually connected to two organic groups. Ordinary silicone rubber is mainly composed of siloxane chains containing methyl and a small amount of vinyl. The introduction of phenyl can improve the high and low temperature resistance of silicone rubber, and the introduction of trifluoropropyl and cyano can improve the heat and oil resistance of silicone rubber. Silicone rubber has good low temperature resistance and can generally work at -55℃. After the introduction of phenyl, it can reach -73℃. The heat resistance of silicone rubber is also outstanding. It can work for a long time at 180℃, and can withstand several weeks or more at a temperature slightly higher than 200℃ and still be elastic. It can withstand high temperatures above 300℃ instantly. Silicone rubber has good air permeability and the oxygen permeability is the highest among synthetic polymers. In addition, silicone rubber also has the outstanding characteristics of physiological inertness and will not cause blood coagulation, so it is widely used in the medical field.
