This specification covers an extreme low-temperature-resistant silicone rubber in the form of sheet, strip, and molded shapes. Primarily for rubber-like parts required to operate or seal from -112 to +446 °F (-80 to +230 °C), compounded especially for operation at extreme low temperatures. Silicone rubber is resistant to deterioration by weathering and by high-aniline-point petroleum-base oils and remains flexible over the temperature range noted. These products are not normally suitable for use in contact with low-aniline-point petroleum-base fluids, including fuels, due to excessive swelling.
