losphthaloyl Choloride CAS：99-63-8

It can be used as a monomer for polyamide, polyester, polyarylester, polyarylamide, liquid crystal polymer, aramid 1313 (Nomex), etc. The downstream product aramid fiber has advantages such as high temperature resistance, flame retardancy, insulation, wear resistance, and good dimensional stability. Currently, it has been widely used in environmental protection, filtration, high-performance protective products, electrical insulation, honeycomb materials for aircraft, high-speed trains, and other fields. It can also serve as a modifier for polymers and an intermediate in the pesticide and pharmaceutical industries.
