Edgetek™ AT Acetal (POM) Formulations

Ideal in precision parts that require high dimensional stability

The Edgetek™ AT product family is a range of unfilled, filled and impact-grade acetal (POM) compounds. Using POM homopolymer or copolymer as the base resin, these materials offer a wide range of physical properties and are often specified where certain key performance issues are critical. Edgetek AT compounds are available pre-colored or can be colored during the manufacturing process with concentrates such as PolyOne’s OnColor™ masterbatches.          


  • Excellent stiffness/toughness, even at low temperatures
  • Very good fatigue endurance
  • Low friction and wear for fewer field failures in moving parts
  • Low moisture absorption makes it ideal for tight tolerances in moist environments.
  • Very good dimensional stability
  • Excellent chemical resistance
  • Cost effective alternative to expensive metal parts.

Additional benefits:  

  • Very good creep resistance
  • Good electrical properties
  • Easily processed by injection molding or extrusion
