PEEK - Polyetheretherketone 

TECAPEEK Ensinger Plastics

PEEK material (chemically known as polyetheretherketone) is manufactured by Ensinger in standard stock shapes for machining and is extruded in sheet, rod and tube using Victrex® PEEK 450G polymer. PEEK is a unique semi crystalline, engineering thermoplastic that also offers excellent chemical compatibility.

Parts manufactured from high temperature plastic PEEK polymer can also operate at temperatures up to 260°C (480°F) and have a melting point around 341°C (646°F). PEEK plastic is often used in hot water or steam environments while maintaining physical properties such as flexural and tensile strength on a high level. Polyetheretherketone is often viewed as one of the engineering thermoplastics that tends to command a high price, however experienced users have come to realise the added value that PEEK materials bring by offering the possibility of manufacturing parts that are lighter, stronger and able to survive longer in harsh environments.
