About This Item

This SAE Aerospace Standard (AS) covers batch qualification procedure for virgin and compounded polytetrafluoroethylene (PTFE) resins used for compression molding. AS9100 requires virgin and modified PTFE as a testing material be representative of production PTFE and/or parts. The testing specified herein is limited to tensile strength, elongation and specific gravity. Any other tests required by the purchaser must be specified separately. This standard provides a PTFE resin batch qualification procedure for tensile strength, elongation and specific gravity to ensure AS9100 compliance. AS9100 requires that any material specification shall be representative of production material and/or parts made from that material. Current ASTM specifications for qualification of batches of PTFE resins limit the qualification procedure, preventing such compliance.
