Difference between pa6 and pa66

Hangzhou Fancheng Chemical Co.,Ltd | Updated: Dec 30, 2016

Both Polyamide 6 (PA6) and Polyamide 66 (PA66) are widely used in many different markets and applications due to their excellent performance / cost ratios. Many parts are made with these polyamides in the Transportation, Electronics & Electrical, Consumer goods, Building & Construction and Packaging industries. They are by far the most used Polyamides globally. Although they exhibit similar properties, slight differences do remain.

PA6 has a slightly lower temperature resistance versus PA66 and is also slightly less expansive.

Compared to PA66 the PA6 exhibits:

  • Better hydrolytic stability

  • Slightly lower cost

  • Better long term heat ageing

  • Slightly lower heat deflection temperature (PA66 HDT at 1.8 MPa is 80-90°C)

  • Similar stiffness at temperature below 180°C
