Polyetheretherketone can be used at very high temperatures (about +260 °C) and it shows extraordinary mechanical strength, toughness, hardness, flexural strength, torsional strength.
PEEK exhibits excellent chemical resistance, very good dielectric properties up to +260 °C, and a very good resistance to all kinds of radiation (even ultraviolet rays only lead to a slight yellow discoloration). PEEK is self-extinguishing properties according to UL 94.
