【Product Introduction】
4,4'-Methylenedianiline(MDA )MDA contains more than 99.0% of 4,4 '- methylenedianiline and a small amount of 2,4' -methylenedianiline. lt is an aromatic diamine mixture.The molecular weight is 198.26 and it is in white or lightyellow solid state at room temperature.MDA as an important chemical intermediate, it can bewidely used in MDl, HMD1,Pl, PE, epoxy resin hardener, performance thermoplastic, chain extender of PU elastomer etc. These products synthesized with it have excellent properties of mechanics, electrical-insulation, heat-resisting, radiation-resisting and abrasion-resisting.
Warehouse and Storage
Warehouse should be dry, ventilated and protected from light. lt is strictly forbidden to be heatedto prevent oxidation. Leakage, sun and rain are strictly prohibited during transportation.
Shelf life
Under the recommended storage conditions, the shelf life is 12 months. The shelf life beyond canstill be used if it is tested to meet the technical specifications.
