PEEK


PEEK

PEEK (polyetheretherketone) is one of the highest performing semi-crystalline thermoplastics available today. PEEK offers a combination of superlative properties that allow it to replace metal in some of the most severe end-use environments.
PEEK is one of the industrial most chemically resistant plastics and offers excellent strength, superior fatigue resistance, and a continuous-use temperature of 240°C (464°F). Exceptional chemical resistance to organics, acids and bases; High mechanical strength in excess of 250°C (482°F); very good wear and abrasion resistance; Best-in class fatigue resistance; Excellent dimensional stability; Excellent resistance to hydrolysis.
