Silicone Rubber

An elastomer made from silicone polymer and silica. Possesses great chemical stability, and an extraordinary degree of heat resistance for a rubber-like material in that it can be used for cable insulations at temperatures up to about 150°C for long periods without any apparent changes. It usually needs some form of external protection to prevent abrasion during installation. Cables of this type are used in specialized applications such as wiring of flues and brick kilns where high temperatures are en­countered.
