Polyamide 11 or Nylon 11 is a polyamide

Polyamide

A polyamide is a polymer containing monomers of amides joined by peptide bonds. They can occur both naturally and artificially, examples being proteins, such as wool and silk, and can be made artificially through step-growth polymerization or solid-phase synthesis, examples being nylons, aramids,...

 under the tradename Rilsan from castor beans. PA 11 is not biodegradable.

Its properties are similar to PA12, 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.
