PEEK 30% Carbon
Overview
What is the Material: PEEK 30% Carbon is a semi-crystalline material filled with carbon fibers.
Key Material Features: This material is beneficial in applications requiring increased mechanical strength, low density, wear resistance, low friction, and dimensional stability, while maintaining many properties of other PEEK materials including chemical resistance and temperature resistance.
Other Considerations: The addition of carbon fibers increases the level of heat conductivity, which is beneficial in sliding applications. Also the carbon fibers increase the materials structural properties like glass filled PEEK material, but this material is not abrasive like glass filled PEEK can be. This material has notable hydrolysis/steam resistance.
