Title:Silicone Rubber, Extreme Low-Temperature Resistant, 35 - 45
Issuing Committee:Ams Ce Elastomers Committee
Scope:This specification covers a silicone rubber in the form of sheet, strip, tubing, extrusions, and molded shapes.Primarily for rubber-like parts required to operate or seal from -112 to +248 °F (-80 to +120 °C), 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.While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
