Polyether Ether Ketone (PEEK)

Polyether ether ketone (PEEK) materials are semi-crystalline, high purity polymers comprising of repeating monomers of two ether groups and a keytone group. PEEK is a high-performance engineering plastic with outstanding resistance to harsh chemicals, excellent mechanical strength and dimensional stability. It offers hydrolysis resistance to steam, water, and sea water. PEEK has the ability to maintain its properties under extreme temperatures and pressures. It is suitable for continuous use at temperatures up to 338F (170C).

PEEK polymer is typically used as a metal replacement in a wide variety of high performance end-use applications. These range in diversity from components for cars, aircraft, industrial pumps, valves and seals, to silicon wafer carriers, connectors and serializable surgical instruments. PEEK is used in high performance application because it has good mechanical properties, including impact resistance, low wear rate, and a low coefficient of friction, but more importantly, these properties are also retained over a wide temperature range.
