PEEK – Polyetherether-Ketone Applications

Polyetherether-Ketone (abbreviated PEEK) is a high performance semi-crystalline thermoplastic. Manufactured from Victrex® resin PEEK’s characteristics include high temperature performance, excellent wear properties, superior chemical resistance, hydrolytic stability and outstanding toughness and strength. PEEK meets many aerospace, automotive, fire, smoke and toxicity, food/water, medical/pharmaceutical, and military approvals and standards.
