Heat resistance: Silicone rubber has much better heat resistance than ordinary rubber, and can be used almost permanently at 150 degrees Celsius without any performance changes; Can be used continuously for 10000 hours at 200 degrees Celsius; It can also be used for a period of time at 350 degrees Celsius.
Cold resistance: Ordinary rubber has a delay of -20 degrees to -30 degrees, while silicone rubber still has good elasticity at -60 degrees to -70 degrees. Some special formulas of silicone rubber can also withstand extremely low temperatures.
Weather resistance: Ordinary rubber rapidly degrades under the action of ozone generated by corona discharge, while silicone rubber is not affected by ozone. Moreover, under long-term exposure to ultraviolet radiation and other climatic conditions, its physical properties only show slight changes.
Electrical performance: Silicone rubber has a high resistivity and its resistance value remains stable over a wide temperature and frequency range. At the same time, silicone rubber has good resistance to high-voltage corona discharge and arc discharge.
Conductivity: When conductive fillers (such as carbon black) are added, silicone rubber has conductivity
Thermal conductivity: When certain thermal conductive fillers are added, silicone rubber has thermal conductivity
Radiation resistance: Silicone rubber containing phenyl greatly improves its radiation resistance
Flame retardancy: Silicone rubber itself is flammable, but when a small amount of flame retardant is added, it has flame retardancy and self extinguishing properties; And because silicone rubber does not contain organic halides, it does not emit smoke or toxic gases during combustion.
Breathability: Silicone rubber film has better breathability than ordinary rubber and plastic waxing film. Another characteristic is its strong selectivity for different air permeability.
