Acetal or Polyoxymethylene (POM) is a high-performance thermoplastic well-suited for a wide range of applications due to its wear characteristics. The material offers excellent strength, stiffness, and creep resistance. We offer various grades of acetal for injection molding, including:

  • Celcon M90
  • 10% Glass Filled Acetal
  • 20% Glass Filled Acetal
