MDI 99.5% methylene diphenyl diisocyanate
1.MDI (Isocyanate) introduction :
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 -20ºC. It is solvent-free form with 2.7 average organic function and maximum of 125 cps (25ºC) viscosity which is mixed with monomer MDI of 4,4-diphenylmethane diisocyante and its oligomer above dimer, trimer and tetramer.
2.MDI (Isocyanate) Specfiication:
MDI physical information
MDI Chemical properities
MDI PM 200 Spec.
TDI 80/20 Spec.
3.Application of MDI
Isocyanates MDI is extensively application in most of field, such as thermal insulation rigid foam, PU coating, PU adhesive,
Seepage-proofing, structure foam, Automobile bumper, high resilience etc.
4.Packing: 200kg/drum
shipping time: within 15 workdays after place the order.
