Nylon 11

Nylon 11 or Polyamide 11 (PA 11) is a polyamide bioplastic derived from vegetable oil. It is produced by Arkema under the trade name Rilsan from castor beans. Nylon 11 is not biodegradable.

Its properties are similar to nylon 12, although it has a lower environmental impact, consumes less non-renewable resources to be produced and has superior thermal resistance. It is weaker but more resilient than the most common types of nylon (6 and 6/6). It is used in high-performance applications such as automotive fuel lines, pneumatic airbrake tubing, electrical anti-termite cable sheathing, oil and gas flexible pipes and control fluid umbilicals, sports shoes, electronic device components, and catheters.
