Application

4,4'-Methylenedianiline is an important chemical intermediate, which is used as raw material for manufacturing diisocyanate, polyamide, antioxidant, corrosion inhibitor, etc; It is the main monomer for the production of carbamate and diisocyanate. It is used as a chain extender for producing high-temperature resistant polyimide enameled wire paint, electrical insulation laminates, polyamides, aerospace high-temperature resistant coatings, heat-resistant polymers, and polyurethane elastomers. The most outstanding properties of the resin or high temperature resistant polymer produced with it are high temperature resistance, good insulation, high strength, good wear resistance and chemical stability. It can be made into thin films, molded products, wire paints, etc. It is also used for inner and outer insulation of heat-resistant cables, interlayer insulation of transformers, and gaskets of motors. It is used as an antioxidant for chloroprene rubber, butyl rubber, natural rubber, and styrene butadiene rubber, with moderate aging protection performance; It is also a strong active agent. It can also be used as a curing agent for epoxy resins, with properties similar to m-phenylenediamine, suitable for castings, laminates, adhesives, and coatings.

Storage

Store in a cool and ventilated warehouse; Store separately from strong oxidants, food, and feed.
