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.
