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. It is one of the few plastics compatible with ultra-high vacuum applications, which makes it suitable for aerospace, automotive, and chemical industries. 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. Grades include virgin (unfilled), glass-filled, bearing, and metal and x-ray detectable grades. PEEK exhibits superior mechanical and electrical properties with a maximum continuous working temperature of 480F to 500F and excellent retention of mechanical properties up to 570F in a steam or high-pressure water environment. with excellent chemical resistance, fatigue resistance and thermal stability. Because of these excellent sliding characteristics, they are used in gears, bearings, sliding bearings, and many other applications. PEEK Plastic Buy PEEK Plastic Online & View All PEEK Rods, Tubes, & Sheets Curbell Plastics Home / Material / PEEK Shop PEEK Online Shop for PEEK sheets, rods, and tubes. PEEK plastic is a temperature-resistant engineered machinable thermoplastic. 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 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. PEEK material (chemically known as polyetheretherketone) is manufactured by Ensinger in standard stock shapes for machining.
