Bearing Grade PEEK
JUTAIPEEK®WR02 is a wear-resistant modified polyether ether ketone profile. WR stands for Wear resistance. WR02 is a PEEK product modified with 20% Teflon. Among them, Teflon is specially customized, which can achieve low lubrication coefficient and high anti-wear rate in the uniform dispersion of polyether ether ketone resin. The product has high abrasion resistance and also has the characteristics of not rubbing off powder. Suitable for electronic appliances, mechanical parts and other fields. 
Product Features
JUTAIPEEK®WR02 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.
