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. It has six common variants, each represented as a separate material. The material properties section shows ranges encompassing all variants. To see the details of each variant on a separate page, follow the links in the Variant Materials section further below.
