Acetal (POM C) / Acetal H

Acetal (POM C)

Copolymer material with exceptional balance of mechanical strength and rigidity, good impact resistance and low moisture absorption, making this material an excellent all round thermoplastic. With its ease of machinability, acetal is an ideal choice for high precision parts, where dimensional stability is important. Capable of working up to 100 deg c, however its wear resistance is lower than nylon 6g.

Acetal H

Homopolymer material often referred to as delrin, has very similar properties to acetal c, but has increased mechanical strength, rigidity and creep resistance plus a lower thermal expansion rate and improved wear resistance. However, in continuous use, acetal c performs at 10 deg °c higher than Acetal H, and is more resistant to hot water and alkalis.

Key Facts:

  • High stability, rigidity & hardness
  • Good impact resistance at low temperatures
  • Low level moisture absorption
  • Physiologically safe
  • Excellent machinability
  • Good creep resistance
  • Not resistant to UV
