This 30 % glass fibre reinforced grade 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 fibres tend to abrade the mating surface.
