Method for the preparation of flexible polymeric foams

摘要

A method for the preparation of a fexible polymeric foam by reacting a polyisocyanate component comprising an isocyanate-containing prepolymer having an NCO-content of from 2 to 15% by weight, with an isocyanate-reactive component comprising water and a polyoxyalkylene polyol having a high ethylene oxide and primary hydroxyl group content.
