Ketron® CA30 PEEK

This 30% carbon fiber reinforced grade (colour: black) combines even higher stiffness, mechanical strength and creep resistance than Ketron GF30 PEEK with an optimum wear resistance. Moreover, compared to unreinforced PEEK, the carbon fibers considerably reduce thermal expansion and provide 3.5 times higher thermal conductivity - dissipating heat from the bearing surface faster, improving bearing life and pressure-velocity capabilities.

Product Overview.

• Very high maximum allowable service temperature in air (250 °C continuously, up to 310 °C for short periods of time)
• High mechanical strength, stiffness and creep resistance, also at elevated temperatures
• Excellent chemical and hydrolysis resistance
• Excellent wear & frictional behaviour
• Very good dimensional stability
• Excellent resistance to high energy radiation (gamma- and X-rays)
• Inherent low flammability and very low levels of smoke evolution during combustion  

Engineering Notes.

The stiffness of all PEEK grades drops off significantly and expansion rate increases above its glass transition temperature (Tg) of 150 °C (300 °F). A material like Duratron^® PAI would be better suited for close tolerance bearings or seals operating at temperatures higher than 150 °C (300 °F).

Proven Applications

Pump Wear Rings

• Ketron PEEK CA30 improves centrifugal pump efficiency by permitting closer running tolerances and eliminating corrosion, galling and wear problems. (Prior material: Bronze)
