Polyamide 6 - Nylon 6 - PA 6 Mineral Filled

Initially developed to imitate the properties of Nylon 6/6, polyamide 6 (PA 6) is a semicrystalline 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.

Polymer Type

Thermoplastic

Advantages

In comparison to unmodified PA 6, mineral filled PA 6 has:

  • Increased tensile strength

  • Higher flexural modulus

  • Strong dimensional stability

  • Higher stiffness

Disadvantages

It also has a number of disadvantages over unmodified PA 6:

  • Significantly reduced notched izod impact strength

  • Lower elongation at break
