What is Polyamide 66?
Polyamide 66 is one of the most versatile engineering thermoplastics. It is popular in every major market using thermoplastic materials. Because of its excellent balance of strength, ductility and heat resistance, nylon 6/6 is an outstanding candidate for metal replacement applications.
PA66 is used when PA6 reaches its limit temperature or when the hydrolytic stability of PA6 is not sufficient anymore. It provides good surface appearance and good weld strength leading to burst pressure resistance. The remaining commercial polyamides, for example, polyamides 11 and 12, and 6, 10, are most used as engineering plastics. For use as an engineering plastic, polyamides are often compounded with fillers, pigments, glass fiber and toughening agents to give specific properties to the polymer.
