Polyamide 6 - Nylon 6 - PA 6 50% Bead Filled

Polyamide 6 (PA 6) was created as an alternative to the patented Nylon 6/6. PA 6 is a semicrystalline polymer and has some similarities to Nylon 6/6 in terms of its properties. It is synthesized in a different way to most other polyamides; ring-opening polymerization rather than condensation polymerization. PA 6 can have glass beads incorporated into its structure to improve certain properties.

Polymer Type

Thermoplastic

Advantages

Compared to unmodified PA 6, bead filled PA 6 has:

  • Increased stiffness

  • Higher strength

  • Higher heat distortion temperature resistance

  • Superior dimensional stability

  • Lower water absorption

Disadvantages

It has only one disadvantage compared to unmodified PA 6:

  • Lower elongation at break
