Polyamide 6 PA6

Swicofil, your expert partner for Polyamide 6 in most diverse grades

Polyamide 6, invented with the intention to copy the characteristics of Polyamide 6.6 without infringing a patent, is a thermoplastic polymer of the Nylon family. 

Although it is very similar to Polyamide 6.6 when it comes to chemical structure and properties, the production of Polyamide 6 fundamentally differs. Whereas almost every Nylon polymer is formed through a condensation reaction (like PA66), Polyamide 6 is synthesized by ring-opening polymerization (of caprolactam). 

As Polyamide 6 and Polyamide 6.6 are very alike, there are only a few differences in terms of application. Compared to PA 66, Polyamide 6 is applied in fields where a lower melting point is required as well as a better dyeability (yarn dyeing). The properties of Polyamide 6 and Polyamide 6.6 can also be combined by the means of copolymer or bicomponent.
