Yuntianhua® SF-10 10% PTFE Filled Pellets Acetal Copolymer
Yuntianhua® SF-10 is a PTFE-filled POM copolymer resin with approximately 10% PTFE. It offers improved friction and abrasion resistance versus standard POM. This grade is ideal for gears, rollers, sliders, and other wear parts used in high-speed, high-load, low-oil, or oil-free conditions.
