Polyamide 11 - Nylon 11 - PA 11

Polyamide 11 (PA 11), sometimes referred to as Nylon 11, is a non-biodegradable, polyamide bioplastic which is derived from vegetable oil. PA 11 is similar in properties to PA 12, however has a number of advantages over it. Compared to the most common Nylon, Nylon 6/6, it is weaker but more lightweight.

Polymer Type



When compared with PA 12, PA 11 has a number of advantages:

  • Low water absorption for a Nylon (c. 2.5% at saturation)  

  • Reasonable UV resistance (compared to other Nylons, not just PA 12)

  • Higher strength

  • Better heat resistance

  • Lower environmental impact

  • Consumes less renewable resources during production


Comparing PA 12 to Nylon 6/6 it has some disdvantages:

  • More expensive  

  • Low impact strength.

  • Lower operating temperature


  • Hose for air, hydraulic fluid or petrol

  • Gears, cams, tool handles

  • Powder coatings for metals e.g. handrails.
