Abstract: A polyol pre-mix containing at least one halogenated hydroolefin blowing agent and having improved shelf life stability is provided, wherein each polyol combined with the halogenated hydroolefin blowing agent has an apparent pH of between 3 and 11.4. Controlling the apparent pH of the polyol(s) enables the polyol pre-mix to be stored for extended periods of time and then used in combination with organic polyisocyanate to produce foam formulations having gel times and tack free times not significantly different from those exhibited when freshly prepared polyol pre-mix is used.

Abstract: The present invention relates to imidazole and/or its derivative as polyurethane or polyisocyanurate foam catalyst in the presence of Low Global Warming Potential (GWP) halogenated olefinic blowing agents, such as the hydrochlorofluoroolefin (HCFO) HCF0-1233zd. More particularly, the present invention relates to catalyst compositions comprising imidazole and/or its derivative. The present invention further relates to the stable pre-blend formulations and resulting polyurethane or polyisocyanurate foams. A method for stabilizing thermosetting foam blends comprises combining: (a) a polyisocyanate and, optionally, isocyanate compatible raw materials; and (b) a polyol pre-mix composition comprising a halogenated olefinic blowing agent, a polyol, a surfactant and a catalyst.
