This specification covers a silicone (VMQ) rubber, reinforced with glass cloth in the form of sheet.

This sheet has been used typically for gaskets or seals requiring a resilient, nonporous sheet material suitable for operations from -67 to +401 \mDF (-55 to +205 \mDC), but usage is not limited to such applications. The material is resistant to deterioration by weathering and aircraft piston 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.
