SAE AMS3657F

SAE AMS3657F – Polytetrafluoroethylene (PTFE) Extrusions Premium Strength As Sintered (Stabilized: Aug 2011)

This specification covers one grade of polytetrafluoroethylene (PTFE) in the form of extruded and sintered rods tubes and profiles.

These products have been used typically for parts such as bushings and insulators requiring chemical inertness up to 500 mDF (260 mDC) and better mechanical and/or electrical properties than AMS 3656 but usage is not limited to such applications. When improved dimensional stability is required it is recommended that stress relieved product in accordance with AMS 3659 be specified. For parts such as seals back-up rings and bearings that do not require dielectric properties and radiographic inspection it is recommended to use AMS 3678/1 Grade B.
