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.
