The crystalline nature of PEEK contributes to its outstanding properties. C = Fair – Moderate Effect, not recommended for continuous use. AvaSpire® AV-722 delivers comparable strength and stiffness to unfilled PEEK at up to 30% lower cost, bridging the gap between PEEK and semi-crystalline polymers like PPS (polyphenylsulfone) and PPA (polyphthalamide). contained herein. Comparable Strength, Stiffness and Chemical Resistance at Lower Cost. Chemical Resistance Chart PN 41-6018/rev.C January 2010. Even when used at 260°C for 5000 hours, the strength is almost the same as in the initial state and excellent in thermal stability. PEEK has a long lifetime in the harshest environments. PEEK is one of the best heat-resistant materials among high performance plastics. PEEK: the benefits . However, PEEK can operate at higher temperatures and retains its excellent mechanical properties at continuous-use temperatures up to 240 °C (464 °F), allowing it to replace metal in severe end-use environments.
Es bietet eine hervorragende Leistung über einen breiten Temperaturbereich und in extremen Umständen.

Kepstan® is a Polyetherketoneketone (PEKK) CoPolymer and is in the family of Poly Aryl Ether Ketone (PAEK) polymers. This chemical res is tance chart is to be used as a guide only. High thermal resistance: PEEK can withstand extreme temperatures of up to 260°C. PEEK has exceptional mechanical, thermal, and chemical resistance properties making it a go-to material in some of the most demanding applications. PEEK wird als eines der besten bestehenden Thermoplasten der Welt angesehen.
Yet PEEK is one of the only materials actually used by industry and companies today.
ThermaX™ PEEK (PolyEtherEtherKetone) is one of the highest-performance polymers in world. * The resistance ratings given for Ertalon®/Nylatron® and Ketron® PEEK are in first instance valid for the unreinforced grades.
