Reducing wear with low-friction polymers

Reduce Friction, Extend Life

In heavily loaded mechanical systems, frictional losses reduce efficiency, cause wear and require heavy maintenance. Thanks to their low coefficient of friction, High Performance Polymers (HPP) ensure smooth, durable and quiet operation, even when dry.

Why aim for a low coefficient of friction?

  • Less energy loss and heat build-up
  • Reduced noise and vibration
  • Reduced maintenance frequency
  • Can be operated without external lubrication
  • Longer component life
