Product Code:SAE AMS3650
Title:Rods, Sheets, and Molded Shapes, Polychlorotrifluoroethylene (Pctfe), Unplasticized
Issuing Committee:Ams P Polymeric Materials Committee
Scope:This specification covers a 100% homopolymer of polychlorotrifluoroethylene (PCTFE) in the form of rods, sheets, and molded shapes. Primarily for parts requiring chemical inertness and high impact strength up to 200 degrees C (392 degrees F) or high-frequency electrical insulating properties up to 165 degrees C (329 degrees F).Product Code:SAE AMS3347
Title:Rubber, Silicone 1200 Psi (8.27 Mpa), High Modulus 45-55
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 parts required to operate or seal from -75 to +205 degrees C (-103 to +401 degrees F), compounded especially for high 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. 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.
