KETRON® PEEK-HPV (PEEK+CF+PTFE+graphite) black
The addition of PTFE, graphite, and carbon fibre produces KETRON® PEEK “bearing grade”.
Excellent tribological properties (low friction, long durability, and high U factor) make this material especially suited for sliding applications characterised by friction and wear.
Specifications
- Extremely high maximum operating temperature in air (+250 °C continuously, with peaks up to +350 °C)
- High mechanical strength, creep resistance and stiffness, even at elevated temperatures
- Excellent chemical and hydrolysis resistance
- Excellent behaviour under wear and friction (in particular for KETRON® PEEK - HPV and CA 30)
- Low intrinsic flammability and extremely low emission of fumes during combustion
- Very good dimensional stability
- Good electrical insulation and dielectric properties (except for KETRON® PEEK - HPV and CA 30)
- Excellent resistance against high energy radiation
