PEEK
Polyetheretherketone (PEEK) is a unique, semi-crystalline, high temperature engineering thermoplastic that can be machined to meet the most demanding applications. PEEK is an excellent material for a wide spectrum of applications where thermal, chemical, and combustion properties are critical to performance. PEEK retains its flexural and tensile properties at very high temperatures, in excess of 250°C (482°F). The addition of glass fiber or carbon fiber reinforcements enhances the mechanical and thermal properties of the basic PEEK material. Medical grades are also available.
