| description | The present invention provides a polyurethane foam and a manufacturing method therefor, the polyurethane foam being a reaction product of a polyester polyol and an isocyanate and having a flame retardancy index (FRI) of 130 or less, wherein the polyester polyol is formed from a composition comprising an alcohol and two or more types of aromatic carboxylic acid including isophthalic acid and phthalic acid. The polyurethane foam can have both improved flame retardancy and heat resistance, and has total heat release and total smoke release that are significantly lower than those of a conventional polyurethane foam, and thus has an excellent fire protection effect when used as an interior material for buildings and low toxic gas generation. |
