Polymeric PM-200 is a diisocyanato-diphenylmethane(MDI)-based composition containing some higher functionality isocyanates. The functionality is about 2.6-2.7. It is brown liquid at ambient temperatures.
COSMONATE M-200 is polymeric MDI, generally used in manufacturing hard and semi-hard polyurethane foam. COSMONATE M-200 is liquefied in normal temperature and easily handled and stored down to -20℃. It is solvent-free form with 2.7 average organic function and maximum of 220 cps (25℃) viscosity which is mixed with monomer MDI of 4,4-diphenyl methane diisocyante and its oligomer above dimer, trimer and tetramer.
