The benefits of Polyamide 6.6 plastic

  • Higher abrasion resistance.
  • It is the strongest aliphatic nylon.
  • Unlike acetal, the addition of glass fiber improves stiffness considerably.
  • Low-temperature toughness.
  • Good fatigue resistance.


Limitations of Polyamide 6.6 plastic

  • Relatively difficult to process due to exceptionally low melt viscosity.
  • High water absorption, though less than PA 6.
  • Post mold shrinkage.
  • Weathering can cause color change and embrittlement unless suitably stabilized.

Polyamide 6.6 plastic – Specific properties

Polyamide 6.6, most typically referred to as nylon 66, is most common in textile and plastic industries. A few of the properties that make this type of plastic suitable for those two industries are:

  • The resistance to toughness and chemicals.
  • Good appearance.
  • Thermal stability.
