Silicone rubber has many excellent properties: Breathability: Silicone rubber film has better breathability than ordinary rubber and plastic wax film. Another feature is that it has strong selectivity for different permeability. Gas exchange membrane medical artificial organs.
Cold resistance: The temperature of ordinary rubber is -20 degrees ~ -30 degrees, that is, silicone rubber still has good elasticity at -60 degrees ~ -70 degrees, and some specially formulated silicone rubber can withstand extremely low temperatures. Low temperature sealing ring.
Weather resistance: Ordinary rubber degrades rapidly under the action of ozone generated by corona discharge, while silicone rubber is not affected by ozone. And its physical properties change only slightly under ultraviolet and other climatic conditions for a long time. Sealing material for outdoor use.
Heat resistance: Silicone rubber has much better heat resistance than ordinary rubber. It can be used almost forever at 150 degrees without performance changes; it can be used continuously for 10,000 hours at 200 degrees; it can also be used for a period of time at 350 degrees. It is widely used in occasions requiring heat resistance: thermos seals, pressure cooker rings, heat-resistant handles.
Electrical properties: Silicone rubber has a high resistivity and its resistance remains stable over a wide range of temperature and frequency. 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, and others.
Conductivity: When conductive fillers (such as carbon black) are added, silicone rubber has a keyboard conductive contact point.
Thermal conductivity: When certain thermal conductive fillers are added, silicone rubber becomes thermally conductive. Heat sinks, thermally conductive sealing pads, thermal conductive rollers for copiers and fax machines.
Radiation: The radiation resistance of silicone rubber containing phenyl 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 becomes flame retardant and self-extinguishing; and because silicone rubber does not contain organic halides, it does not emit smoke or toxic gases when burned, and is suitable for various occasions with strict fire protection.
