Polyamide (PA, Nylon) 11
PA 11 is a thermoplastic, further classified as a polyamide (or Nylon) plastic. It has a moderately low density and can have a moderately high ductility among thermoplastics.
The properties of PA 11 include two common variations. This page shows summary ranges across both of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare PA 11 to: polyamide plastics (top), all thermoplastics (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
