PEEK - Polyetheretherketone
PEEK is a high-performance, high-temperature semi-crystalline thermoplastic. This most famous and important member of the polyetheretherketone group combines excellent wear resistance and very good mechanical properties, even under thermal stress. PEEK plastic is often used in the environments with the presence of hot water or steam, where it maintains its physical properties, for example high bending and tensile strength. Its property profile is complemented by excellent chemical resistance and high operating temperatures (up to 250°C). Therefore, it is an almost universally applicable material for highly stressed parts. Its excellent dimensional stability in combination with high creep strength underlines the suitability of PEEK plastic for use even in the most sophisticated machined parts. AFINIS Group® sells PEEK plastics in the form of rods, sheets and tubes.
