Material: PEEK Bearing Grade- Ketron® PEEK HPVThe addition of carbon fibres, graphite and PTFE to virgin PEEK results in a "bearing grade" Ketron® PEEK . Excellect chemical resistance, hydrolosis resistance, inherent low flammability, outstanding dimensional stability, operating temperature range (-30°c-+250°c), resistance against high energy radiation, mechanical strength/stiffness and wear resistance make this grade especially suited for bearings and wear application.
