    Abstract: According to one embodiment of the present invention, predominantly closed cell polymer foams are provided which comprise less than 13.5% Z-1336mzz, carbon dioxide and one or more of methyl formate, methylal and trans-dichloroethylene and has a k factor of less than 0.147 BTU-in/hr-ft2-° F. The cellular polymer foam is foamed polyurethane or foamed polyisocyanurate, depending on the identity of the polyisocyanate and active hydrogen-containing compound reactants and their relative amounts. “Active hydrogen” means that the hydrogen is reactive with the isocyanate of the polyisocyanate reactant. The active hydrogen-containing compound contains at least two groups that contain active hydrogen (atoms) that is reactive with isocyanate. The polyurethane and polyisocyanurate reaction products (foamed) resulting from the process of the present invention are polymers. The reaction product can be a mixture of these polymers.

    Abstract: Disclosed is a mixture comprising the compound Z-1-chloro-2,3,3,3-tetrafluoroprop-1-ene and at least one additional compound selected from the group consisting ofHFOs, HFCs, HFEs, CFCs, CO2, olefins, organic acids, alcohols, hydrocarbons, ethers, aldehydes, ketones, and others such as methyl formate, formic acid, trans-1,2 dichloroethylene, carbon dioxide, cis-HFO-1234ze+HFO-1225yez; mixtures of these plus water; mixtures of these plus CO2; mixtures of these trans 1,2-dichloroethylene (DCE); mixtures of these plus methyl formate; mixtures with cis-HFO-1234ze+CO2; mixtures with cis-HFO-1234ze+HFO-1225yez+CO2; mixtures with cis-HFO-1234ze+HFC-245fa; and azeotrope or azeotrope-like compositions. Also disclosed are methods of using the compositions as blowing agents, solvents, heat transfer compositions, aerosol propellant compositions, fire extinguishing and suppressant compositions.

    Abstract: The present application provides foams having improved insulation and thermal performance and processes of forming said foams. Exemplary foams described herein are prepared according to a process comprising reacting or extruding a foamable composition comprising (i) a compound selected from E-CHCl═CHCF3, Z—CF3CH═CHCF3, and E-CF3CH═CHCF3, or any mixture thereof, and (2) a C5 hydrocarbon (e.g. cyclopentane), under conditions effective to form the foam.
