POLYURETHANE FOAM COMPOSITION CAPABLE OF FORMING AN ENVIRONMENT-FRIENDLY POLYURETHANE HEAT INSULATOR, AND A POLYURETHANE FOAM PRODUCED THEREFROM

摘要

PURPOSE: A polyurethane foam composition and a polyurethane foam produced therefrom are provided to producing the polyurethane foam with an improved insulation ability.;CONSTITUTION: A polyurethane foam composition contains polyol, polyisocyanate, a catalyst, a surfactant, a foaming agent and fluorinated carbonate. The fluorinated carbonate includes an endothermic peak appearing at 18~30 deg C which the full width at half maximum is 4.5~5.5. The freezing point of the fluorinated carbonate is -10~40 deg C. The foaming agent is hydrocarbon. The content rate of the fluorinated carbonate is 0.1~10 parts by weight for 100 parts of polyol by weight.;COPYRIGHT KIPO 2010
