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. 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: PEEK plastic is a semicrystalline engineering thermoplastic of the polyaryletherketone (PAEK) family with high-temperature tolerances, strength, and stability across harsh environments. Unfilled PEEK natural is the most balanced material in high temperature environments, where non-lubricated sliding and non-contamination is required. 9 min read Polyether ether ketone (PEEK) plastic is a highly coveted engineering material, thanks to its superb blend of strength, resistances, and workability. 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. The formation and properties of PEEK transfer films on steel and sapphire are studied by in-situ observations of PEEK wear process, contact temperatures and triboemission, as well as FTIR and Raman spectroscopies ex situ. The material used in this study is ThermaX PEEK developed by 3DXTECH for 3D printing applications (3 DXTECH, 2021).The nominal glass transition temperature, T g, of this material is 143 ☌ and the nominal melt temperature, T m, is 343 ☌.Several samples were fabricated based on the geometry shown in Fig.
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.
