![]() ![]() Implants: fixation plates and screws for the vertebral column, joint implants. Medical: multiple sterilised chirurgical apparatus. Oil and gas industry: (underwater)piping and connectorsĪnalytical Apparatus: piping in HPLC apparatus Industry: piping, chains, electric heat insulation and connectors and pump housings Injection mouldable at temperatures between 360 and 400 ☌.Īviation: metal replacement on all kinds of components such as hinges, matrix in thermoplastic fiber composites for military planes, piping. Because of the very high processing temperature can only be coloured by certain inorganic dyes. continuous up to 260 ☌.Ĭhemical resistance: Very good resistance against virtually every substance, even at high temperatures, with the exception of concentrated sulphur. Thermal properties: Tg around 150 ☌, Tm 340 ☌. Very good ductility and excellent wear permanence, especially in specifically developed composites. 100 MPa), with glass or carbon fiber much higher. Mechanical properties: Very high Young’s Modulus (3600-4200 MPa), very high strength (approx. PEEK is generally considered as the highest quality processable polymer and the application possibilities are only limited by the very high cost of resin.ĭensity: 1.30 g/cm3, higher when filled with fibers. The high purity makes medical applications like implants and applications in high vacuum possible. PEEK also has an excellent chemical resistance, a very low combustibility and very good fire, smoke and toxicity properties, important for aviation applications. Even when it is unreinforced PEEK has a very high strength and Young´s Modulus, combined with high ductility. It can be used at extremely high temperatures, such as a constant temperature of 260 ☌ or briefly up to 300 ☌ (the melting point is around 340 ☌). The sliding behavior always depends on the overall sliding system, and on parameters like sliding partner, load, sliding speed, surface roughness, temperature and so on.Polyetheretherketon is a very high-quality semi-crystalline polymer with exceptional properties. The fillers carbon fiber and graphite make TECAPEEK PVX black a superior bearing grade with improved thermal conductivity. The better the thermal conductivity of the part, the faster the heat is dissipated and overheating can be reduced. In order to avoid thermal overload of a bearing, the resulting frictional heat should be dissipated as quickly as possible from the sliding surface of the bearing. Because of these excellent sliding characteristics, they are used in gears, bearings, sliding bearings, and many other applications. PEEK is used where conventional materials (POM, PA / Nylon etc.) would be beyond their limits. With this combination of criteria, this bearing grade material can be used in harsh environments of 100 to 300☌. Improved heat dissipation (reduced frictional heat).Still, many applications call for special PEEK bearing grades as TECAPEEK PVX black, containing a multiple filler system (graphite, carbon fiber and PTFE), to fulfill a combination of requirements: Unfilled PEEK natural is the most balanced material in high temperature environments, where non-lubricated sliding and non-contamination is required. PEEK bearing materials with excellent heat resistance and durability 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 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. It provides a unique combination and range of high performance properties. It is a linear, aromatic, semi-crystalline polymer widely regarded as one of the highest performing thermoplastics in the world. Parts manufactured from high temperature plastic PEEK polymer can also operate at temperatures up to 260☌ (480☏) and have a melting point around 341☌ (646☏). PEEK Materials Properties Guide VICTREX PEEK polymer provides exceptional performance over a wide range of temperatures and extreme conditions. PEEK is a unique semi crystalline, engineering thermoplastic that also offers excellent chemical compatibility. It is extruded in sheet, rod and tube that may use Victrex® PEEK 450G or Solvay KetaSpire® KT-820 polymer. PEEK material (chemically known as polyetheretherketone) is manufactured by Ensinger in standard stock shapes for machining. ![]()
