PEEK grades offer chemical and hydrolysis resistance similar to PPS, but can operate at higher temperatures. Virgin PEEK offers steam and wear resistance, while carbon-reinforced PEEK provides excellent wear capabilities.PEEK can be used continuously to 480°F (250°C) and in hot water or steam without permanent loss in physical properties. For hostile environments, PEEK is a high strength alternative to fluoropolymers. PEEK carries a V-0 flammability rating and exhibits very low smoke and toxic gas emission when exposed to flame.
Available Materials (click material for data sheet when available)
EP030 – Carbon Filled PEEK, the addition of carbon fibers enhances the comressive strength and stiffness of PEEK, and dramatically lowers its expansion rate. It offers designers optimum wear resistance and load carrying capability in a PEEK based product. This grade provides more thermal conductivity than unreinforced PEEK, increasing heat dissipation from bearing surfaces improving bearing life and capability.
EP031 – Glass Filled PEEK, the addition of glass fibers significantly reduces the expansion rate and increases the flexural modulus of PEEK. This grade is ideal for structural applications that require improved strength, stiffness or stability, expecially at temperatures above 300°F (150°C).
EP032 – Carbon Fiber with graphite and PTFE filled PEEK, offers the lowest coefficient of friction and the best machinability for all PEEK grades. An excellent combination of low friction, low wear, high LPV, low mating part wear and easy machining, make it ideal for aggressive service bearings.
EP033 – Virgin PEEK, general purpose grade offers the highest elongation and toughness of all PEEK grades. PEEK can be FDA compliant.
