cosmonate m-200 is a polymeric mdi commonly used in the manufacture of hard rigid and semi-rigid polyurethane foam. cosmonate m-200 liquefies at room temperature and is easy to handle and store in containers at -20°c. it is in solvent-free form with an average organic functionality 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.
