PEEK grades offer chemical and hydrolysis resistance similar to PPS, but can operate at higher temperatures. PEEK offers steam and wear resistance, while carbon-reinforced PEEK provides excellent wear capabilities. PEEK can be used continuously to 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-O flammability rating and exhibits very low smoke and toxic gas emission when exposed to flame.
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, especially at temperatures above 150°C.
