Polyamide (PA, Nylon) 4/6 (46)

PA 4/6 is a thermoplastic, further classified as a polyamide (or Nylon) plastic. It can have a moderately high tensile strength relative to other thermoplastics in the database.

The properties of PA 4/6 include six common variations. The property values on this page show ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare PA 4/6 to: polyamide plastics (top), all thermoplastics (middle), and the entire database (bottom). The length of each bar shows the given value as a % of the largest value in the relevant set.
