Ketron® GF30 PEEK

This 30% glass fiber reinforced grade (colour: brownish-grey) offers a higher stiffness and creep resistance than Ketron 1000 PEEK and has a much better dimensional stability. This grade is very appropriate for structural applications carrying high static loads for long periods of time at elevated temperatures. The suitability of Ketron GF30 PEEK for sliding parts, however, is to be carefully examined since the glass fibers tend to abrade the mating surface.

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).
