PEEK

PEEK material (chemically known as polyetheretherketone) is manufactured in standard stock shapes for machining. It is extruded in sheet, rod and tube that may use Victrex® PEEK 450G or Solvay Ketaspire® KT-820 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 because it maintains physical properties such as flexural and tensile strength at a high level despite the severe environment. Polyetheretherketone is often viewed as one of the engineering thermoplastics that tends to command a high price, however experienced users have come to realize the added value that PEEK materials bring, by offering the possibility of manufacturing parts that are lighter, stronger and able to survive longer under harsh conditions.

PEEK polymer is a high performance plastic material with an excellent balance of physical properties. It has one of the highest levels of heat resistance and mechanical strength available among plastics. It is also one of the best choices when looking for good chemical resistance, as well as radiation resistance.

PEEK exhibits excellent resistance to various organic solvents, oils, weak acids and alkalis, and can maintain strength over a wide temperature range and concentration. It has proven to be a polymer that is difficult to discolour, expand or break.
