The thermal stability of Silicone Rubber is probably it's most important asset. Components made from these rubbers are affected only to a small extent by extremes of temperature, ranging from -90ºC to +250ºC (depending on grade). Even at temperatures as high as +300ºC, 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 400ºC to 500ºC leaving an intert, non-flammable and electrically non-conductive residue. The Silicone Sponge Sheet supplied br PAR is of a fine cellular construction, composed mainly of non-interconnecting cells and normally of an off-white colour. There are many applications for Silicone Sponge Sheeting, but for continuous use they will withstand temperatures between -60ºC and +200ºC.
