Reinforced with 30% fiberglass offers greater rigidity and creep resistance than Ketron PEEK 1000® and has much better dimensional stability. Ketron Peek GF30® is very suitable for structural applications that carry high static charges for long periods of time at high temperatures. The application of the Ketron GF30 PEEK® to sliding parts, however, should be carefully examined, since the glass fibers tend to wear out the contact surface.
