Ketron® Peek 1000 is a general purpose, unreinforced grade of PEEK (polyetheretherketone). It offers the highest elongation and toughness of all unreinforced PEEK grades. All grades of PEEK offer excellent chemical and hydrolysis resistance similar to PPS (polyphenylenesulfide), but can operate at higher temperatures. With a V-0 flammability rating PEEK can be used continuously to 480 degrees F. in hot water and/or steam without permanent loss of physical properties. PEEK 1000 offers steam and wear resistance and is now available black making ideal for instrument components where aesthetics are important. Carbon-reinforced grades provide excellent dimensional stability and increased wear properties at higher loads. A new bearing grade; PEEK HPV offers superior bearing and wear performance at elevated pressure and velocity (PV) levels. PEEK HPV is an excellent alternative to bearing grade fluoropolymers, it also works well for seal components where ductility and inertness are important.
