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
Thermoplastic
Advantages
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
Disadvantages
Comparing PA 12 to Nylon 6/6 it has some disdvantages:
Applications
-
Hose for air, hydraulic fluid or petrol
-
Gears, cams, tool handles
-
Powder coatings for metals e.g. handrails.
