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. 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 products made of this material can still maintain excellent properties in continuous use in high temperature and high pressure water.PEEK material (chemically known as polyetheretherketone) is manufactured by Ensinger in standard stock shapes for machining. When the dose of γ irradiation reaches 1100mrad, it can still maintain good insulation performance.Ĩ.Hydrolytic resistance: PEEK and its composites are not affected by the chemistry of water and high pressure water vapor. In common chemicals, only concentrated sulfuric acid can dissolve or destroy it, and its corrosion resistance is similar to that of nickel steel.Ĥ.Flame retardant: PEEK is a very stable polymer, 1.45MM thick sample, without any flame retardant, it can reach the highest flame retardant standard.ĥ.Peel resistance: PEEK has good peel resistance, so it can be made into thin or electromagnetic wire, and can be used in harsh conditions.Ħ.Fatigue resistance: PEEK has the best fatigue resistance of all resins.ħ.Radiation resistance: the ability of high radiation resistance is very strong, which exceeds that of polystyrene with the best radiation resistance. In particular, the self-lubricating performance of PEEK modified by carbon fiber and graphite in a certain proportion is betterģ.Chemical resistance (corrosion resistance): PEEK has excellent chemical resistance. ![]() In particular, its excellent fatigue resistance to alternating stress is the most outstanding of all plastics, comparable to alloy materials.Ģ.Self lubricity: PEEK has outstanding sliding properties in all plastics and is suitable for applications with strict requirements of low friction coefficient and wear resistance. 1.Mechanical properties: PEEK is a kind of plastic with both toughness and rigidity.
