GEHR Plastics POM-C Acetal
Categories: Polymer; Thermoplastic; Acetal (Polyoxymethylene, POM)

Material Notes: Polyoxymethylene can be used in temperatures up to 100°C. The high surface strength is only surpassed by a few materials. POM shows good sliding properties and high resistance to wear and tear because of the high strength and smooth surface. There is a very low risk of stress cracks. POM-C exhibits a high thermal stability and a high resistance to chemicals.

Properties:

  • no microporosity
  • high strength
  • high rigidity
  • high thermal stability
  • low water absorption
  • high dimension stability
  • good electrical insulating properties
  • very good sliding properties
  • high resistance to stress cracks
  • not resistant to high concentrated acids
  • difficult to glue and paint
Applications include bearings, fittings, gear wheels, parts for pumps, screws, bobbins, parts for textile industry, and medium for coating lines.
