Product Code:SAE AMS3659
Title:Polytetrafluoroethylene Extrusions, Premium Strength, Sintered and Stress-Relieved
Issuing Committee:Ams P Polymeric Materials Committee
Scope:This specification covers virgin, unfilled polytetrafluoroethylene resin in the form of extruded rods, tubes, and shapes. These products have been used typically for parts, such as seals, back-up rings, bearings, and insulators, requiring chemical inertness and dimensional stability up to 260 degrees C (500 degrees F) than AMS 3657 and better mechanical and electrical properties than AMS 3656, but usage is not limited to such applications.
