White crystal. The adipic acid is mainly used to produce nylon 66 fibers and nylon 66 resin, polyurethane foam plastics. The adipic acid is mainly used to produce nylon 66 fibers and nylon 66 resin, polyurethane foam plastics.In organic synthesis industry, it is generallyserve as base material of adiponitrile and hexamethylenediamine . Meanwhile it is used in the production of lubricants and plasticizer, and also used in medicine etc.

By far the majority of the 2.5 billion kg of Adipic Acid produced annually is used as monomer for the production of nylon by a polycondensation reaction with hexamethylene diamine forming 6, 6-nylon.
Other major application also involve polymers: It is a monomer for production of Polyurethane and its esters are plasticizers, especially in PVC.
