Form: This specification covers a silicone rubber in the form of sheet@ strip@ tubing@ extrusions@ and molded shapes. Application: Primarily for rubber-like parts required to operate or seal from -65??o +205??(-85??o +400 0F). Silicone elastomer is resistant to deterioration by weathering and petroleum-base lubricating oil and remains flexible over the temperature range noted. These products are 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.
