Polymethylene polyphenylisocyanate that contains MDI. Used in coatings. Possesses a high reactivity and a high diphenylmethane diisocyanate content. Suits to a wide variety of applications where demolding and processing times must be kept at a minimum.
Polymethylene polyphenylisocyanate containing MDI. Possesses a
high functionality and a relatively high viscosity. Used in polyisocyanurate rigid foams. Provides good resistance to heat distortion, very good strength properties at low densities and improved humid age stability.
Polymethylene polyphenylisocyanate containing MDI. Possesses a
narrow molecular weight distribution and high reactivity. Offers compatibility with rigid polyether and polyester polyols.
