![]() 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 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. Seriously - we know this first hand.PEEK material (chemically known as polyetheretherketone) is manufactured by Ensinger in standard stock shapes for machining. ![]() ![]() Please make sure to purge out your extruder before it cools down or you run the risk permanent clogs. Please note - PEEK has a tendency to stick to metal (PEEK loves metal).Lower than 0.25mm may create too much back pressure in the hot end and result in poor feeding, jams, drive gear clicking, and eating a notch into the filament. We do not recommend printing layers below 0.25mm with carbon fiber grades. Layer Height: Ideal layer height is 60% of nozzle diameter.We strongly recommend our Hardened Steel Nozzles Nozzle: We strongly recommend a 0.4mm orifice or larger.Here are our recommendations - which should act as a good starting point for you and your particular set-up. We developed Nano Polymer Adhesive specifically for PEEK, in the beginning! One of the more difficult aspects of printing with PEEK was getting it to stick to the build plate. Every printer / slicer is different and you will need to tinker a bit to find a process that works for you. PEEK has a melt temperature (Tm) of 343☌, therefore, you will need an all-metal extruder capable of reaching (and holding) temps upwards of 400☌ or more depending on your specific printer. Heat Deflection Temperature (HDT) 280☌ĬarbonX™ CF-PEEK is carbon fiber reinforced and abrasive - resulting in high wear on a brass nozzles.Continuous Use Temperature (CUT) 240 - 260☌.Glass Transition Temperature (Tg) 143☌.General thermal properties of PEEK+CF10 are: PEEK has an excellent resistance to hydrolysis in boiling water and superheated steam (sterilization/autoclave) at temperatures in excess of 250☌ (482☏).
