Polyhexamethylene adipamide, commonly known as PA66, is a thermoplastic resin that is generally made from the condensation of adipic acid and hexamethylene amine.It insolubles in general solvents, only solubles in m-benzol, etc. It has the characteristics of high mechanical strength and hardness. It can be used as engineering plastics, mechanical accessories such as gears and lubricating bearings. It can also replace non-ferrous metal materials to make machine shells, automotive engine blades, etc., and can also be used to make synthetic fibers.
