Initially developed to imitate the properties of Nylon 6/6, polyamide 6 (PA 6) is a semi-crystalline thermoplastic polymer. Its production was due to the patenting of Nylon 6/6 and the requirement for a material that had similar characteristics. Unlike other polyamides usually formed by condensation polymerization, PA 6 is formed by ring-opening polymerization. PA 6 can be reinforced by the inclusion of minerals in its structure giving it a distinct set of properties.

Advantages When Compared to Unmodified PA 6

  • Increased tensile strength
  • Higher flexural modulus
  • Strong dimensional stability
  • Higher stiffness

Disadvantages When Compared to Unmodified PA 6

  • Significantly reduced notched izod impact strength
  • Lower elongation at break
