ABSTRACT:
This invention relates to polyurethane foam moldings prepared by reacting a specific polyisocyanate with a polyol in the presence of water as the primary blowing agent, wherein the polyisocyanate comprises a specific polyisocyanate mixture of a NCO-terminated prepolymer prepared employing poly(oxytetramethylene)glycol ("PTMG") with polymethylene polyphenyl polyisocyanate ("Polymeric MDI"), or a specific NCO-terminated prepolymer prepared from the reaction of an organic polyisocyanate containing Polymeric MDI as an essential component with PTMG. The polyurethane foam moldings have excellent abrasion resistance and can be useful for automotive steering wheels, headrests, armrests and the like.
