The benefits of Polyamide 4.6 plastic

  • High-temperature resistance than other PA materials.
  • Excellent mechanical properties.
  • Chemical resistance.
  • Excellent fatigue properties and low creep.
  • High water absorption


Limitations of Polyamide 4.6 plastic

  • PA 4.6’s moisture absorption is higher than those of standard polyamides 6 and 6.6 due to the more polar backbone.
  • The material is more sensitive to stress cracking due to the higher crystallinity.
