Polyamide 6 - Nylon 6 - PA 6 High Impact

Polyamide 6 (PA 6) is a semicrystalline polyamide initially developed in order to emulate the properties of Nylon 6/6 without the violation of its patent. It is formed via ring-opening polymerization, which is unusual for a polyamide as they are typically formed via condensation polymerization. Modifications to PA 6 can be made to increase it's impact toughness.

Polymer Type

Thermoplastic

Advantages

When compared to unmodified PA 6, high impact PA 6 has a number of advantages:

  • Better-notched izod impact toughness

  • Superior elongation at break

Disadvantages

It also has some disadvantages:

  • Reduced tensile strength

  • Lower flexural modulus
