Product Description

 

Product Description

 

MDA-100 is an aromatic diamine mixture containing more than 99.0% 4,4 '-diaminodiphenylmethane and slight 2,4' -diaminodiphenylmethane. The molecular weight is 198.26, and it is white or light yellow solid granule at room temperature.

MDA-100 as an important chemical intermediate, it can be widely used in MDI, HMDI,PI, PEI, 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.
