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 (VMQ) rubber reinforced with glass cloth. This product has been used typically for gaskets or seals requiring a thin, resilient, nonporous sheet material suitable for operating from -55 to +205 degrees C (-67 to +401 degrees F), but usage is not limited to such applications. This material is resistant to deterioration by weathering and petroleum-base engine oil and remains flexible over the temperature range noted. This material is not normally suitable for use in contact with gasoline or aromatic fuels and low-aniline-point petroleum-base fluids due to excessive swelling of the elastomer.
