Process for producing synthetic resin foam, blowing agent and premix |
摘要 |
The present invention relates to a process for producing a synthetic resin foam which comprises reacting at least one polyol with at least one polyisocyanate compound in the presence of an organic blowing agent, wherein the organic blowing agent is a blowing agent for synthetic resin foams which is characterized by being a mixture comprising 1,1,1,3,3-pentafluorobutane (HFC-365mfc) and at least one halogen-containing compound and optionally containing at least one member selected from the group consisting of glycol compounds and amide compounds. Also provided are: a premix comprising the blowing agent and a polyol mixture; and a process for producing a synthetic resin foam from these.
