    • A foam expansion agent composition is disclosed that includes water and a hydrohaloolefin of the formula CF3CX═CHY, wherein X is selected from the group consisting of H, Cl and F, and Y is selected from the group consisting of H, Cl, F, CF3 and CF2CF3. Also disclosed is a foam-forming composition that includes the foam expansion agent composition of this disclosure and an active hydrogen-containing compound having two or more active hydrogens. Also disclosed is a closed-cell polyurethane or polyisocyanurate polymer foam prepared from reaction of an effective amount of the foam-forming composition of this disclosure and a suitable polyisocyanate. Also disclosed is a process for producing a closed-cell polyurethane or polyisocyanurate polymer foam. The process involves reacting an effective amount of the foam-forming composition of this disclosure and a suitable polyisocyanate. Also disclosed is a process for using the closed-cell polyurethane or polyisocyanurate polymer foam of this disclosure. The process involves using such polymer foam at a temperature of no more than about the normal boiling point of the hydrohaloolefin which is used in the preparation of such polymer foam.

    • An improved closed cell polymer foam and foaming agent involving the use of a hydrogen-containing halocarbon blowing agent (e.g., HCFC-22) in combination with an effective amount of a hydrogen bond forming blocking agent (e.g., organic ether, ester or ketone). The presence of the blocking agent is shown to significantly reduce the escape of blowing agent from and entry of air into the foam resulting in low thermal conductivity over a longer period of time and improved thermal insulation value. The present invention further relates to compositions comprising a blowing agent and an active hydrogen-containing compound, commonly referred to in the art as B-side compositions or blends, and using such compositions for producing polyurethane and polyisocyanurate foams in which the blowing agent comprises a major proportion of 1,1,2,2-tetrafluoroethane (HFC-134).
