Abstract

The present invention pertains to the field of polyurethane, especially relates to an isocyanate-terminated prepolymer, the method for preparing the same and the use thereof. The present invention adjusts the reaction components and the ratios thereof to obtain an isocyanate-terminated prepolymer suitable for preparing flexible polyurethane foam under a relative low mold temperature. The method for preparing flexible polyurethane foam by using the isocyanate-terminated prepolymer provided in this present invention can reduce the mold temperature, production time and energy consumption, as well as to obtain a polyurethane flexible foam processing good physical and mechanical properties.
