PEEK-WR Granules
PEEK wear-resistant modified granules are specialty modified products developed by adding solid lubricants or wear-resistant fillers such as PTFE, graphite, carbon fiber, and MoS₂. These grades dramatically reduce the friction coefficient of PEEK (as low as 0.15~0.25) and significantly improve wear resistance (wear rate reduced by 1~2 orders of magnitude), while retaining PEEK's inherent high-temperature and chemical resistance. Pellet color varies depending on filler. The ideal material choice for moving frictional components.

Performance Features:
1)Extremely low friction coefficient (0.15~0.30); superior to most engineering plastics
2)Outstanding wear resistance; wear rate reduced by over 90% vs. pure resin
3)High pv-value load capacity; suitable for dry friction & boundary lubrication
4)Low creep; excellent dimensional stability under long-term loading
5)Capable of long-term operation without lubrication; outstanding maintenance-free property
6)Food contact compliant (select grades; FDA compliant)
Application:
1)Mechanical Industry: Oil-free bearings, thrust washers, guide rings, piston rings
2)Automotive Systems: Transmission bearings, ABS system parts, throttle body parts
3)Fluid Power: Mechanical seal rings for pumps, gear pump side plates, compressor piston rings
4)Precision Instruments: Printer/copier gears, scanner drive components
5)Food Packaging: FDA-compliant grades for food processing wear parts
