- Issuing Committee
- Content
- This specification covers one grade of polytetrafluoroethylene in the form of extruded and sintered rods, tubes, and shapes. These products have been used typically for parts, such as seals, back-up rings, bearings, bushings and insulators, requiring chemical inertness up to 260 degrees C (500 degrees F) and better mechanical and/or electrical properties than AMS 3656, but usage is not limited to such applications. When dimensional stability is required, it is recommended that stress relieved product in accordance with AMS 3659 be specified.
