    摘要: The present invention is directed towards a method of stabilizing thermosetting foam blends such as polyurethane poly blends containing a blowing agent with negligible (low or zero) ozone-depletion and low GWP based upon unsaturated halogenated hydroolefins in which one or more ester is added to the thermosetting foam blends. The thermosetting foam blends typically in clued: polyol(s); surfactant(s); catalyst(s); flame retardent(s); organic acid inhibitor(s)/stabilizer(s); carbon dioxide generating agent(s). The addition of the one or more esters to the thermosetting foam blends was unexpectedly found to result in blends which were stable over time and the resulted foams have a uniform cell structure with little or no foam collapse.
