Polyamide (PA) or Nylon: Complete Guide (PA6, PA66, PA11, PA12…)

Final Markets and Applications of Polyamide/Nylon Products

Plastic parts made with polyamides find use in various industries. These include transportation, electronics & electrical, consumer goods, building & construction, and packaging. They can also be a good alternative to metal when filled with glass fibers. Explore the applications where polyamides have proven to be the material of choice.


Key Applications

Applications of PA 6 & PA 6-6

PA 6-6 is used when PA 6 reaches its temperature or hydrolytic stability limit. It provides good surface appearance and weld strength leading to burst pressure resistance. The molding cycles are quick, providing an economic interest. Polyamide 6 and Polyamide 6-6 answer the requirements of many applications.
