    4,4'-Methylenedianiline used as curing agent of epoxy resin, antioxidant and antioxidant of rubber, also used as vulcanization accelerator of rubber and latex, and used as thiazole accelerator and active agent in natural rubber and styrene-butadiene rubber It is also used to make diisocyanates, polyamides, etc. It is the main monomer for the production of polyurethane and diisocyanate. Used to make polyimide high temperature enameled wire paint, electrical insulation laminates, polyamides, aerospace high temperature paints, heat resistant polymers and polyurethane elastomers as chain extenders. The most prominent properties of the resin or high temperature polymer produced by it are the advantages of high temperature resistance, good insulation, high strength, good abrasion resistance and chemical stability. Can be made into films, molded products, paints for wires, etc. Used for internal and external insulation of aircraft and rocket heat-resistant cables, interlayer insulation of transformers, motor gaskets, etc.
