PEEK (polyetheretherketone) is a high-performance engineering plastic with outstanding resistance to harsh chemicals. The mechanical properties and flexural modulus of PEEK are among the highest of all plastic resins. PEEK’s properties provide resistance to abrasive and fatigue wear, while also providing high strength and excellent resistance to high temperatures. The chemical resistance in PEEK is outstanding, even at elevated temperatures, resisting most common organic compounds and is not attacked by water or pressurized steam. Glass and carbon fillers can increase strength and thermal stability. Unfilled PEEK generates extremely low levels of smoke and toxic gas emission in fire situations. Because of its superior properties, PEEK is actively used in metal replacement applications.
PEEK has a long list of outstanding properties:
