Flexible foams and flexible molded foams based on liquid isocyanate-terminated allophanate-modified MDI prepolymer blends and processes for the production of these foams

摘要

This invention relates to flexible foams and flexible molded foams prepared from an isocyanate blend comprising an allophanate modified MDI, a polyether polyol, and a polymethylene poly(phenyl isocyanate). The present invention also relates to processes for the production of these flexible foams and flexible molded foams.
