PEEK is a semicrystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained to high temperatures. Polyetheretherketone can be used at very high temperatures (+480 °F) and it shows an extraordinary mechanical strength, toughness, hardness, flexural strength, torsional strength. PEEK exhibits excellent chemical resistance, very good dielectric properties up to +480 °F and a very good resistance to all kinds of radiation. Importantly it is self-extinguishing according to UL 94.
