Discover why Delrin® is a widely used engineering thermoplastic for gears

Delrin® combines low-friction and high-wear resistance with high-strength and stiffness for applications ranging from automotive components to office automation equipment. Plus, Delrin® acetal homopolymers (Polyoxymethylene POM) successfully replaces metals—even in fine critical gears—with superior quality.

Performance You Can Count On

No matter what type of gear you design—spur, helical, bevel, worm, rack and pinion or planetary gearsets—you can count on Delrin® for:

  • Low friction for smooth operation
  • Low noise for a better user experience
  • Long life fatigue performance for reliability
  • Lightweight for increased efficiency and user comfort
  • Cost-effective manufacturing with higher yields and faster throughput
