POLYURETHANE FOAM COMPOSITION WITH EXCELLENT INSULATION PROPERTY OF A RIGID POLYURETHANE FOAM AND A POLYURETHANE FOAM PREPARED USING THE SAME

摘要

PURPOSE: A polyurethane foam composition is provided to prepare a polyurethane foam with excellent insulation property without the increase of the thickness of the polyurethane foam. CONSTITUTION: A polyurethane foam composition comprises, based on 100.0 parts by weight of polyol, 100-120 parts by weight of isocyanate, 1-5 parts by weight of catalyst, 0.5-4.5 parts by weight of surfactant, 1-3 parts by weight of chemical blowing agent, 10-20 parts by weight of physical blowing agent, 0.1-10 parts by weight of nucleating agent, and 0.005-0.15 parts by weight of silsesquioxane-based compound. The silsesquioxane-based compound is a fluorinated silsesquioxane.
