Ketron® GF30 PEEK SP 30% glass fiber reinforced grade and offers higher stiffness and creep resistance than Ketron® 1000 PEEK SP and has better dimensional stability. This grade is appropriate for structural applications carrying high static loads for long periods of time at elevated temperatures. Ketron® GF30 PEEK SP is suitable for sliding parts but should be carefully examined as the glass fibers tend to abrade the mating surface.
