This specification covers a silicone rubber in the form of sheet, strip, tubing, molded shapes, and extrusions. These products have been used typically for parts required to operate or seal from -90 to +205 degrees C (-130 to +400 degrees F), compounded especially for high strength, but usage is not limited to such applications. Silicone elastomer is resistant to deterioration by weathering and aircraft piston engine oil and remains flexible over the temperature range noted. This rubber 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.
