1, heat resistance: silicone rubber than ordinary rubber has much better heat resistance, can be used at 150 degrees almost forever without performance changes; It can also be used continuously for 10,000 hours at 200 degrees; It can also be used for a period of time at 350 degrees;
2, cold resistance: ordinary rubber temperature: -20 degrees ~-30 degrees, that is, silicone rubber in -60 degrees ~-70 degrees still has good elasticity, special formula of silicone rubber can also withstand extremely low temperature;
3, weather resistance: ordinary rubber rapidly degrades under the action of ozone generated by corona discharge, while silicone rubber is not affected by ozone. Under ultraviolet light and other climatic conditions for a long time, its physical properties only change slightly.
4, electrical properties: silicone rubber has a high resistivity and its resistance remains stable in a wide temperature and frequency range. At the same time, silicone rubber has good resistance to high voltage corona discharge and arc discharge.
5, electrical conductivity: when adding conductive fillers (such as carbon black), silicone rubber has electrical conductivity.
6, thermal conductivity: When adding some thermal conductive fillers, silicone rubber has thermal conductivity.
7, radiation resistance: the radiation resistance of silicone rubber containing phenyl is greatly improved.
8, flame retardant: silicone rubber itself is flammable, but when adding a small amount of flame retardant agent, it has flame retardant and self-extinguishing; And because silicone rubber does not contain organic halides, it does not smoke or emit toxic gas when burning.
9. Permeability: silicone rubber film has better permeability than ordinary rubber and plastic waxing film. Another feature is that it has a strong selectivity for different air permeability.
