What Is PEEK Plastic?
PEEK plastic, also known as polyetheretherketone, is ideal for components used in harsh environments that require excellent chemical resistance over a wide range of temperatures. PEEK is engineered resin designed to perform well applications that require and hydrolysis resistance while maintaining stiffness with PEEK temperature limits up to 170°C / 338°F.

Grades of PEEK Plastic
PEEK, Unfilled Virgin
Naturally abrasion resistant, unfilled, virgin PEEK material provides wear and steam resistance. Of all the PEEK grades, unfilled PEEK provides the greatest toughness and elongation.
PEEK, 30% Glass-Fiber-Reinforced, 30% Glass-Filled PEEK
30% glass-filled PEEK offers a reduced expansion rate and increased flexural modulus. Ideal for structural applications looking for stiffness and stability at higher temperatures.
PEEK, 30% Carbon-Fiber Reinforced
Carbon fiber reinforced PEEK increases wear-resistance, greater thermal conductivity and a lower expansion rate.
PEEK, Graphite Reinforced Bearing Grade
Bearing grade PEEK reinforced with graphite and PTFE lubricants offers low friction, low wear, high LPV and low mating part wear.
