Overview :

PEEK (polyether ether ketone) is a semi-crystalline thermoplastic. As a special polymer material, PEEK has high temperature resistance and good chemical resistance, excellent electrical properties, and flame retardant ( UL94 V-0). PEEK maintains its excellent dimensional stability and good mechanical properties in a long time under high temperature steam environment.  The good comprehensive performance of PEEK makes it possible to replace traditional materials such as metals and ceramics in some fields to improve the comprehensive performance of products, and make the products lighter. PEEK can be used to a wide range of applications such as: high-precision aircraft parts, auto parts, and bearings in the industrial field, gaskets, sealing rings, surgical instruments in the medical field, extrusion into sheets and bars, etc. Shop for PEEK Rods & Sheets >>
