    Abstract: The present invention relates to foam products made with blowing agent compositions comprising at least one hydrochlorofluoroolefin (HCFO) used in the preparation of Namable thermoplastic compositions. The HCFOs of the present invention include, but are not limited to, 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd), particularly the trans-isomer, 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf), dichloro-fluorinated propenes, and mixtures thereof. The blowing agent compositions of the present invention are used with coblowing agents including carbon dioxide, atmospheric gases, hydrofluorocarbons (HFC), hydrofluoroolefins (HFO), alkanes, hydrofluoroethers (HFE), and mixtures thereof. Preferred HFCs used as coblowing agents in the present invention include, but are not limited too, 1,1,1,2-tetrafluoroethane (HFC-134a), 1,1-difluoroethane (HFC-152a), 1,1,1-trifluoroethane (HFC-143a), pentafluorethane (HFC-125), difluoromethane (HFC-32). The blowing agent compositions are useful in the production of low density insulating foams with improved k-factor.

    Abstract: Disclosed is a combination of hydrofluoroolefins and/or hydrochlorofluoroolefins with stabilizers wherein the stabilizers minimize the degradation of the hydrofluoroolefins and hydrochlorofluoroolefins during storage, handling and use yet allow for atmospheric degradation. The combinations exhibit low or zero ozone depletion potential and lower global warming potential making them of interest as replacements for chlorofluorocarbons and hydrfluorocarbons. The combinations of the present invention comprise hydrofluoroolefins and/or hydrochlorofluoroolefins in combination with a stabilizer or stabilizers selected from free radical scavengers, acid scavengers, oxygen scavengers, polymerization inhibitors and combinations thereof.

    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) HCFO-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, wherein the catalyst comprises substituted imidazole having C2 or greater substitutions at the N1 nitrogen and/or its derivative. The resultant polyurethane or polyisocyanurate foams have uniform cell structure with little or no foam collapse.
