RIGID POLYURETHANE FOAM-MOLDING COMPOSITION AND METHOD FOR PRODUCING RIGID POLYURETHANE FOAM BY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a rigid polyurethane foam-molding composition capable of improving low temperature dimensional stability easily with an inexpensive way in the rigid polyurethane foam by using a hydrofluorocarbon (HFC) singly as a foaming agent, and a method for producing the same. SOLUTION: This method for producing the rigid polyurethane foam is provided by using 0.01-20 pts. mass compound having an unsaturated bond and a carbonyl group adjacent to the bond as a modifying additive based on 100 pts. mass organic polyisocyanate or polyol.
