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.
