| The thermal stability of silicone rubber is probably its most important asset. Components made from these rubbers are affected only to a small extent by extremes of temperature, ranging from –90°C to 250°C (depending on grade). Even at temperatures as high as 300°C Silicone rubber will operate for limited periods. Silicone rubber is an excellent electrical insulating material. Resistance to arcing corona, ultra-violet light and ozone is good. It decomposes at 400°C to 500°C leaving an inert, non-flammable and electrically non-conductive residue. It is made of a fine cellular construction composed mainly of non-interconnecting cells and are normally of an off-white color. For continuous use it will stand temperatures between –60°C and -200°CInformation provided by P & P Technology |
