Polyether ether ketone (PEEK) 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.
PEEK retains its flexural and tensile properties at very high temperatures in excess of 250°C (482°F).
PEEK has greater strength and rigidity than many of the other engineering thermoplastics, making it tough over a wide range of temperatures.
The addition of glass fiber or carbon fiber reinforcements enhances the mechanical and thermal properties of the basic PEEK material.
Due to its robustness, PEEK is used to fabricate items used in demanding applications, including bearings, piston parts, pumps, high-performance liquid chromatography columns, compressor plate valves, and electrical cable insulation. It is one of the few plastics compatible with ultra-high vacuum applications.
