Form: This specification covers a silicone rubber in the form of sheet@ strip@ tubing@ molded shapes@ and extrusions. Application: Primarily for rubber-like parts required to operate or seal at temperatures from -90??o +205??(-130??o +400 0 F)@ compounded especially for high strength. Silicone elastomer is resistant to deterioration by weathering and aircraft piston engine oil and remains flexible over the temperature range noted. The 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.
