RESIN PREMIX COMPOSITION, RIGID POLYURETHANE FOAMING COMPOSITION AND RIGID POLYURETHANE FOAM |
摘要 |
An object of the invention is to provide resin premix compositions which include a polyol and a hydrocarbon foaming agent while still exhibiting good storage stability, the polyol being obtained without the use of ring-opening polymerization reaction of a cyclic ether. The resin premix composition of the invention includes at least a polyol and a hydrocarbon foaming agent, the polyol including a polyether ester polyol (A) obtained by reacting a polyether polyol with a fatty acid and/or a fatty acid ester, the polyether polyol being obtained by condensing a polyhydric alcohol including 50 mol % or more of a trihydric or higher alcohol. |
