About Acetal / POM (Polyoxymethylene)
Acetal offers high stiffness and strength, low friction and wear, excellent dimensional stability and good chemical resistance, ideal for moving mechanical parts and precision components. Homopolymer is about 10–15% stronger and stiffer; copolymer holds up better in hot water and in alkaline (high-pH) and chlorinated solutions. POM has a narrow processing window and is attacked by strong acids and oxidizing agents, including chlorinated water over time.
Common applications
- Gears, cams and bearings
- Snap-fits and fasteners
- Fluid-handling and pump components
- Conveyor and automation parts
- Precision mechanical components

A polymer chemist reviews every request, then matches your grade or finds a qualified equivalent and prices it.
What to send for an accurate quote
- The grade name, from any supplier, or a data sheet
- Color (natural, black or a custom match)
- Fill type and percentage, if any
- Melt flow, if you know it
- Quantity for this order and what you use in a year
- Ship-to city and state or province
Homopolymer or copolymer, quoted to your spec
Send the POM type, melt flow and any wear or FDA requirement, and a polymer chemist returns a matched grade and quote.
