Ammonium dodecanedioate is primarily used in the production of high-performance polymers, particularly polyamides and polyesters. It serves as a key intermediate in the synthesis of nylon 6,12, which is valued for its excellent mechanical properties, chemical resistance, and thermal stability. This material is widely employed in automotive components, electrical connectors, and industrial coatings due to its durability and ability to withstand harsh environments. Additionally, it finds application in the formulation of adhesives and sealants, where it enhances bonding strength and flexibility. In the textile industry, it is utilized to create fibers with improved moisture resistance and wear characteristics. Its role in specialty coatings also contributes to corrosion protection and surface finishing in various industrial applications.
