How much do you know about silicone rubber? Follow the editor of customized mold silicone rubber For sale to have a simple understanding!
Silicone rubber refers to a rubber whose main chain consists of alternating silicon and oxygen atoms, and two organic groups are usually attached to the silicon atoms. Ordinary silicone rubber is mainly composed of siloxane chain links containing methyl groups and a small amount of vinyl groups. The introduction of phenyl groups can improve the high and low temperature resistance of silicone rubber, while the introduction of trifluoropropyl and cyano groups can improve the temperature and oil resistance of silicone rubber. Silicone rubber has good low-temperature resistance, and generally can still work at -55°C. After the introduction of phenyl, the temperature can reach -73°C. Silicone rubber also has outstanding heat resistance. It can work 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 in an instant. Silicone rubber has good air permeability, and its oxygen transmission rate is the highest among synthetic polymers. In addition, silicone rubber also has outstanding characteristics of physiological inertness and does not cause blood coagulation, so it is widely used in the medical field.
