Polyamide was originally developed for nylon stockings. Today, in addition to textiles, the material is also used for plastic products, where there are high demands for chemical resistance and durability.
Polyamide is a thermoplastic, crystalline material group. Polyamide is also known by the trade name nylon. A distinction is made between the various polyamides by means of a code number. If the individual segments are different, it is described with a set of numbers (e.g. PA66). PA6 and PA66 constitute the vast majority of the consumption in polyamides.
