High and low temperature resistance
Of all rubbers, silicone rubber has the widest operating temperature range (-100 ~ 350℃). For example, after the appropriate coordination of vinyl silicone rubber or low phenyl silicone rubber, after 250℃ for thousands of hours or 300℃ for hundreds of hours of hot air aging can still remain elastic; Low phenyl silicone rubber vulcanized rubber after 350℃ for tens of hours after hot air aging can still maintain elasticity, its glass transition temperature of -140℃, the vulcanized rubber at -70 ~ 100℃ temperature is still elastic. Silicone rubber can withstand thousands of degrees of instantaneous high temperature when it is used as thermal insulation coating on the inner wall of rocket nozzle.
