Heat resistance: Silicone rubber has much better heat resistance than ordinary rubber, and can be used almost always at 150 degrees without performance changes; it can be continuously used for 10,000 hours at 200 degrees; it can also be used at 350 degrees a period of time. Widely used in occasions requiring heat resistance: thermos sealing ring, pressure cooker ring heat-resistant handle

Cold resistance: ordinary rubber is -20 degrees to -30 degrees late, that is, silicone rubber still has good elasticity at -60 degrees to -70 degrees, and some special formula silicone rubber can withstand extremely low temperatures. Low temperature seal

Weather resistance: ordinary rubber is rapidly degraded by the ozone generated by corona discharge, while silicone rubber is not affected by ozone. And under long-term ultraviolet and other climatic conditions, its physical properties have only changed slightly. Sealing material for outdoor use

Electrical properties: Silicone rubber has a very high electrical resistivity and its resistance remains stable over a wide range of temperatures and frequencies. At the same time, silicone rubber has good resistance to high voltage corona discharge and arc discharge. High-voltage insulators, TV high-voltage caps, electrical parts, other

Electrical conductivity: When conductive fillers (such as carbon black) are added, silicone rubber has conductive contact points for the keyboard

Thermal conductivity: when some thermal conductive fillers are added, silicone rubber has thermal conductivity heat sink thermal conductive gasket thermal rollers for photocopiers and fax machines

Radiation: The radiation resistance of silicone rubber containing phenyl groups is greatly improved. Electrical insulation cables, connectors for nuclear power plants, etc.

Flame retardancy: Silicone rubber itself is flammable, but when a small amount of flame retardant is added, it is flame retardant and self-extinguishing; and because silicone rubber does not contain organic halides, it does not emit smoke or emit toxic gases when burned. Various fire prevention occasions

Air permeability: Silicone rubber film has better air permeability than ordinary rubber and plastic waxing film. Another feature is its strong selectivity to different air permeability. Gas exchange membrane medical supplies artificial organs
