Material Data Sheet
Material: Tecapeek™
PolyetheretherketoneTecapeek™ is a unique, semi-crystalline, high temperature engineering thermoplastic. It is an excellent material for a wide spectrum of applications where thermal, chemical, and combustion properties are critical to performance. Especially significant in this regard is Tecapeek™'s ability to retain its flexural and tensile properties at very high temperatures in excess of 482°F. This material has been used in applications such as automotive, marine, nuclear, oil well, electronics, medical and aerospace. Tecapeek™ offers exceptional chemical resistance and outstanding wear and abrasion resistance.
