MATERIAL GUIDE
POM
Delrin® / Acetal
We specialize in POM machining — custom CNC machining of acetal homopolymer and copolymer grades, including Delrin®. POM offers high stiffness, low friction and excellent machinability for precision mechanical parts.
Key Properties
High stiffness and strength
Low friction and wear
Excellent machinability
Good dimensional stability
Low moisture absorption
Typical Applications
Gears and pulleys
Bushings and bearings
Precision mechanical parts
Valve and pump components
Fasteners and clips
Machining Capabilities
POM machines cleanly with tight tolerances, making it ideal for precision components. Prototypes and production runs available.
FAQ：
Q: What is the difference between Delrin and acetal?
A: Delrin® is a homopolymer acetal from DuPont; other acetal grades are usually copolymers. Both machine well and we stock both.
Q: Is POM good for gears?
A: Yes — POM’s low friction and high stiffness make it a first choice for gears and moving parts.
Q: Does POM absorb water?
A: Very little — POM keeps stable dimensions even in humid environments.
