Title:Silicone (Vmq) Rubber, Lubricating Oil and Compression Set Resistant, Electrical Grade, 55-65
Issuing Committee:Ams Ce Elastomers Committee
Scope: This specification covers a silicone (VMQ) rubber in the form of sheet, strip, tubing, extrusions and molded shapes. Primarily for parts required to operate or seal from -55 to +230 degrees C (-67 to +446 degrees F), compounded especially for aircraft piston engine oil resistance, low compression set, and controlled dielectric strength. Silicone elastomer is resistant to deterioration by weathering and by high-aniline-point petroleum-base oils and remains flexible over the temperature range noted. The elastomer 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.
