PEEK / Lion Engineering Plastics

PEEK Unfilled

Material tradenames include Susta® PEEK, Ketron® PEEK 1000, TecaPEEK, ZL® 1500, & Unitrex.

PEEK grades offer chemical and hydrolysis resistance similar to PPS, but can operate at higher temperatures. PEEK 1000 offers steam and wear resistance, while carbon-reinforced PEEK provides excellent wear capabilities. Our latest grade, PEEK HPV, offers outstanding bearing performance. 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-O flammability rating and exhibits very low smoke and toxic gas emission when exposed to flame.

Toughness of all PEEK grades. The newly available black PEEK 1000 is ideal for instrument components where aesthetics are important, as well as for seal components where ductility and inertness are important. Available in Sheet & Rod

PEEK Glass-filled

Material tradenames include Susta® PEEK GF30, Ketron® PEEK GF30, TecaPEEK™ GF30, & Unitrex.

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 300°F (150°C). Available in Rod.

PEEK Carbon Filled

Material tradenames include Susta® PEEK CF30, Ketron® PEEK CA30, TecaPEEKCF30, & Unitrex.

PEEK Bearing Grade

Material tradenames include Susta® PEEK MOD, Ketron® PEEK HPV, TecaPEEK™ PVX, & Unitrex.

Carbon fiber reinforced with graphite and PTFE lubricants, our newest grade of 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. Available in Tube
