Cosmonate M-200 is a polymeric MDI commonly used in the production of hard and semi-hard polyurethane foam. Cosmonate M-200 is liquefied at normal temperature, easy to handle and stored at temperatures down to -20 ° C. This species does not contain a solvent, performs an organic function on average 2.7 and has a viscosity of 220 cps (25 ° C). Mixed with monomeric MDI 4,4-diphenylmethane diisocyanate and its oligomers above the dimer, trimer and tetramer.
