In fact, PEEK is among the worlds highest performing thermoplastics and is widely used in the aerospace, automotive, and chemical industriesįor a multitude of engineering parts such as gears, bushes, friction bearings, shafts, ball valve seals, and small precision (rotational) parts. This material can replace steel in many applications. 1 However, it exhibits only moderate resistance to weathering due to damage caused by UV radiation.īecause of PEEK’s excellent mechanical properties, including high stiffness, high toughness, outstanding wear resistance, and long-term creep and fatigue resistance, mechanical parts made of Steam and can be used continuously up to 500☏ (260☌) with little or no permanent loss of its physical properties. Its exceptionally high resistance to hydrolysis in hot water and PEEK posesses high thermal stability, excellent chemical resistance, and The aromatic ring structure connected to ketone groups provides high modulus and long-term thermal oxidative stability whereas the ether linkages provide toughness, ductility and Semi-crystalline, cololess high-performance engineering 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.Polyether Ether Ketone (PEEK) Properties and Applications 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. PEEK OMEGA-PEEK Polyetheretherketone (PEEK) is semi-crystalline advanced material exhibits a unique combination of high mechanical properties, temperature. PEEK was first conceived in 1978 relatively recently by manufacturing standards as a high-temperature resistant material for cable insulation. Because of PEEKs excellent mechanical properties, including high stiffness, high toughness, outstanding wear resistance, and long-term creep and fatigue.
With this combination of criteria, this bearing grade material can be used in harsh environments of 100 to 300☌. Know Your Materials: Polyetheretherketone (PEEK) By Fast Radius June 21, 2021.
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 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 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. 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 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. The design of various 3D printing (3DP) parameters had a significant impact on its mechanical and thermal properties. PEEK material (chemically known as polyetheretherketone) is manufactured by Ensinger in standard stock shapes for machining. Poly-ether-ether-ketone (PEEK) was one of the most promising engineering plastics, which had been widely employed in the aerospace, biomedical and automotive industry and manufacturing.
