Product Description

GEHR PEEKTM

Polyetheretherketone can be used at very high temperatures (about +500 °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 +500 °F and a very good resistance to all kinds of radiation (even ultraviolet rays only lead to a slight yellow discolouration). PEEK is self-extinguishing properties according to UL 94.
