PEEK (Polyetheretherketone) offers good wear resistance and can be used continuously to 250°C in hot water or steam without permanent loss of physical properties. PEEK plastic sheets and rods are very chemically resistant with inherently low flammability and smoke emission. PEEK is very dimensionally stable, resulting in close tolerance machining applications, and is an excellent option for applications requiring little to no outgassing.
