Polyoxymethylene [POM]

Also known as Poliasetal, this engineering thermoplastic is used in precision components that require high rigidity, low friction, and excellent dimensional stability.

Grades

● Ertacetal™ C / Acetron™ GP POM-C
● Ertacetal™ H / Acetron™ H
● Ertacetal™ H-TF / Acetron™ AF Blend

  • High mechanical strength, stiffness and hardness
  • Excellent resilience
  • Good creep resistance
  • High impact strength, even at low temperatures
  • Very good dimensional stability [low water absorption]
  • Good sliding properties and wear resistance
  • Excellent machinability
  • Good electrical insulating and dielectric properties
  • Physiologically inert [several grades are suitable for food contact]
  • Not self-extinguishing
  • POM materials generally have limited UV resistance. Their use is therefore not recommended in applications exposed to direct sunlight or outdoor conditions unless UV-stabilized grades are used.
  • Gear wheels with small modules
  • Cams
  • Heavily loaded bearings and rollers
  • Bearings and gears with tight clearances
  • Valve seats
  • Snap-fit assemblies
  • Dimensionally stable precision parts
  • Electrically insulating components
