Atomfair Methylene Diphenyl Diisocyanate MDI C15H10N2O2
Description Methylene Diphenyl Diisocyanate (MDI), CAS 279262-11-2, is a high-purity aromatic diisocyanate with the molecular formula C15H10N2O2. Its IUPAC name, 1-isocyanato-4-[(4-isocyanatophenyl)methyl]benzene , reflects its symmetrical structure featuring two reactive isocyanate groups. This versatile monomer is a critical raw material in polyurethane production, offering exceptional compatibility with polyols to form rigid foams, elastomers, adhesives, and coatings. Our MDI is synthesized under stringent quality controls to ensure low hydrolyzable chloride content, minimal impurities, and consistent reactivity. Supplied as a stable, moisture-sensitive solid or liquid (depending on isomer), it requires storage under dry, inert conditions to prevent premature polymerization. Ideal for industrial R&D…
