  • Excellent combination of toughness, stiffness, fatigue strength and creep resistance (spring material).
  • Good moisture and chemical resistance.
  • Useful in a wide temperature range.
  • Resistant to thermal and oxidative degradation.
  • Good resistance to stress relaxation.
  • Good friction and wear properties.
  • Low gas and vapor permeability.
  • Tight tolerances and good dimensional stability of finished details.
  • Qualities with different fillers and additives are available to suit different purposes.
  • Attacked by strong mineral acids (pH below 4).
  • Hard to glue with itself or other materials.
  • Should not be used in electrical applications above + 70 ° C.
  • High combustion rate, dangerous gas is formed.

Specific properties

The homopolymer POM-H offers about 10% better mechanical properties but these tend to decrease after prolonged use. In hot water or at elevated ambient temperature, the homopolymer POM-H tends to degrade rapidly.
