3,3′-Diaminobenzidine

Also known as 3,3′,4,4′-tetraaminobiphenyl (abbreviation DAB) is a high-grade polymer monomer that has been researched and applied in developed countries in recent years, especially in aerospace and military-developed countries. It is mainly used for the synthesis of heat-resistant polymer resins and synthetic fibers. The polymer resins and fibers synthesized by them have high heat resistance, flame retardancy, dimensional thermal stability, chemical stability at high temperatures, and wearing comfort. Special performance is unmatched and replaced by other materials, so the development of DAB products is receiving widespread attention from the international industry including China. DAB (3,3’4,4′-tetraaminobiphenyl) is a high molecular monomer which can be used as a polymer material having excellent synthesis performance.
