Wear-resistant Grade PEEK
JUTAIPEEK®WR01 is a type of Polymeric Profiles with high grade wear-resistance. It is made from 10% of short-cut Carbon Fiber, 10% of PTFE Powder, 10% of Graphite Powder modified Polyetherether Ketone (PEEK) (JUTAIPEEK®WR01 is VICTREXTM PEEK Polymers 450FC30 raw material extruded profile).
With low frictional coefficient and low wear rate, JUTAIPEEK®WR01 is a kind of bearing grade PEEK-based composites that has self-lubricating property. It can be applied as Polymeric bearings, gears, and dynamic seals, especially for the demand of low noise level, low vibration and contact to corrosion medium.
Product Features
JUTAIPEEK®WR01 type Wear-resistance Grade PEEK profiles:
● Outstanding sliding and wear performance.
● Excellent strength and stiffness.
● Excellent dimensional stability and low thermal expansion.
● High thermal endurance and the long service temperature is 250℃.
● Outstanding chemical-resistance.
