Cosmonate M-200 is polymeric MDI, usually used to make hard Rigid and semi-rigid polyurethane foam. Cosmonate M-200 is liquefied at room temperature, easy to handle and stored in containers at -20°C. It is in solvent-free form with an average organic function of 2.7 and a maximum of 125 cp (25°C) with monomeric MDI and dimers, trimers and tetramers of 4,4′-diphenylmethane diisocyanate The above oligomers are mixed.
