This document has been declared "Stabilized" and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist.This specification covers a silicone (PVMQ) rubber in the form of sheet, strip, tubing, extrusions, and molded shapes.These products have been used typically for parts required to operate or seal from -85 to +230 degrees C (-121 to +446 degrees F), compounded especially for operation at extreme low temperatures, but usage is not limited to such applications.Silicone rubber is resistant to deterioration by weathering and by high-aniline-point petroleum-base oils and remains flexible over the temperature range noted.This material is not normally suitable for use in contact with low-aniline-point petroleum-base fluids, including fuels, due to excessive swelling.
