PEEK
Polyetheretherketone can be used at very high temperatures (about +260 °C) and it shows an 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 discolouration of its self-extinguishing properties according to UL 94.
