A high performance plastic material with one of the highest levels of heat resistance and mechanical strength available among plastics.
PEEK is an outstanding advanced material for demanding applications where excellent mechanical performance under extreme conditions is a pre-requisite. It 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 realise the added value that PEEK materials bring by offering the possibility of manufactured parts that are lighter, stronger and able to survive longer periods under harsh conditions.
PEEK is an extremely tough, wear resistant plastic with excellent resistance to high temperatures and energy radiation. It is very dimensionally stable and has a high mechanical bearing strength. PEEK rod also offers excellent chemical resistance and a high resistance to hydrolysis, even against super-heated steam. It is also electrically insulating, has good sliding properties and is easily machined. PEEK can be used for thousands of hours at high temperature in steam or high pressure water environments while showing no significant degradation. Radiation resistance is also exceptional. During combustion, the levels of smoke and toxic acid gas released are the lowest of any thermoplastic.
PEEK has a wide operating range of -60°C to +250°C and is insoluble in all common solvents and has excellent resistance to a very wide range of organic and inorganic liquids, even at higher temperatures.
