PEEK

Supplied byIn2Plastics- Last Updated on Jun 2, 2025

PEEK by In2Plastics is a natural/beige-grey colored, high performance, semi-crystalline, flame retardant polyetheretherketone (PEEK) grade. Exhibits superb dimensional stability, good toughness and low modulus of elasticity. Offers excellent chemical-, high energy radiation-, hydrolysis-, impact and high temperature resistance (up to 310°C). Recommended for seals, valves, wear plates and piston rings. PEEK complies with EU food contact and FDA regulations.
