    • 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.
