PTFE-filled POM-H. Due to the filling material, its characteristics are different from those of the POM-C and POM-H base materials. Due to the PTFE content, it is softer and not as rigid. Conversely, its sliding and wear properties are excellent. Even in the event of large loads and small speeds, sliding without “stick-slip” can be achieved.
