COMPARATIVE STRESS RELAXATION TESTS FOR TWO GRADES OF POLYTETRAFLUOROETHYLENE

Abstract

The mechanical relaxation stiffness of two grades of polytetrafluoroethylene (PTFE) are compared using the ERDE stress relaxation test. The materials are an unfilled PTFE and a filled PTFE. For short loading times the filled PTFE is found to be the stiffer material, but in the long term the unfilled PTFE has a better performance.
