Introduction To The Characteristics And Uses Of Silicone Rubber Products

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

(2) Cold resistance: Ordinary rubber is delayed at -20 degrees to -30 degrees, that is, silicone rubber still has good elasticity at -60 degrees to -70 degrees, and some specially formulated silicone rubbers can withstand extremely low temperatures. temperature.

(3) Weather resistance: Ordinary rubber degrades rapidly under the action of ozone generated by corona discharge, while silicone rubber is not affected by ozone. And under ultraviolet light and other climatic conditions for a long time, its physical properties will only change slightly. Sealing materials for outdoor use

(4) Electrical properties: Silicone rubber has a high resistivity and its resistance value remains stable in 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 Insulator TV High Voltage Cap Electrical Parts Others

(5) Conductivity: When conductive fillers (such as carbon black) are added, silicone rubber has conductive contact points for keyboards

(6) Thermal conductivity: When some thermal conductive fillers are added, silicone rubber will have thermal conductivity. Heat sink, heat conduction gasket, copier, fax machine heat conduction roller

(7) Radiation: The radiation resistance of phenyl-containing silicone rubber is greatly improved, and electrical insulation cables, connectors for nuclear power plants, etc.

(8) 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 emit poisonous gas when burning . All kinds of strict fire prevention occasions

(9) Air permeability: Silicone rubber film has better air permeability than ordinary rubber and plastic waxed film. Another feature is that it has strong selectivity to different air permeability. Gas Exchange Membranes Medical Products Artificial Organs
