PEEK (Polyetheretherketone) is a partially crystalline thermoplastic material, which, thanks to its unique properties, is suitable for many applications with high requirements. It is distinguished by high crystallinity and excellent mechanical strength.

PEEK can be used at very high temperatures (around application 260°C) and exhibits extraordinary mechanical strength, hardness, ductility, tensile strength, and torsional strength. PEEK has excellent chemical resistance, very good dielectric properties up to +260°C and very good resistance to various types of radiation (ultraviolet even lead to only a slight yellow discoloration, its self-extinguishing properties in accordance with DIN and UL 94.
