POM absorbs very little moisture and possesses superior mechanical properties. It has excellent dimensional stability as well as good insulating and dielectric properties that allow it to withstand heat over a long period of time. For applications of short duration, it can reach temperatures of up to 150oC, and up to 110oC for longer periods. POM becomes brittle at temperatures below -40oC, it can be reinforced with fibreglass or mineral charges to increase rigidity and solidity.

POM properties include,

  • High strength, stiffness and surface hardness
  • Good dimensional stability and toughness
  • Resistance against fatigue, solvent, fuel, abrasion, wear and friction.


POM is widely used in the mechanical, chemical, electrical and aviation sectors. It is particularly suitable for substituting metal precision components in technical uses such as wheelwork, levers, bearings, screws, coils, textile, machine components, pipe fittings, hot water or fuel pump components and manufactured articles.
