Title:Silicone (PVMQ) Rubber, Extreme-Low-Temperature Resistant, 75 - 85
Issuing Committee:Ams Ce Elastomers Committee
Scope:This specification covers a silicone (PVMQ) rubber in the form of sheet, strip, tubing, extrusions, and molded shapes. Primarily 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. 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.
