Acetal

cnc machined acetal part

Acetal (chemically known as polyoxymethylene or POM) is a high-strength, low-friction engineering plastic with excellent wear properties in both wet and dry conditions. It is chemically resistant to hydrocarbons, solvents, and neutral chemicals. Easy to machine, acetal is an excellent choice for applications requiring complex geometries and tight tolerances.

Acetal offers the following benefits:

  • High strength, rigidity, and toughness
  • Good impact strength, even at low temperatures
  • Low moisture absorption (0.8% at saturation)
  • Outstanding wear resistance and sliding properties
  • Easy to machine
  • Great creep resistance
  • High dimensional stability
  • Good resistance to Hydrolysis up to approximately 140°F
  • Excellent resilience and recovery elasticity

Acetal Applications:

  • Sliding components like bearings, bushings, rollers, and wear guides
  • Electrical insulation parts
  • Components exposed to water
  • Numerous components in food, pharmaceutical, and medical technology industries
