PEEK (Poly Ether Ether Ketone) Materials
ROC Carbon offers a portfolio of PEEK thermoplastic grades that provide good chemical resistance and excellent physical properties for applications including bearings, seals and other parts. Material grades are available as finished parts per your specifications or as raw material blanks for machining.
- Good chemical resistance to alkalis, aromatic hydrocarbons, halogenated hydrocarbons, alcohols, greases, and oils
- Thermal stability
- Contamination resistance
- Mechanical strength
Raw Material Availability
- Solid cylinders up to 20 inch diameter
Technical support is available to help select the proper grade for your application, and engineering services can be provided for designing the finished product.
