#$%^&*AU2017204059A120170706.pdf#####ABSTRACT 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 5 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 10 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 15 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. 201/3 8.0 e Lk 7.0 75U -~ 6.5 6.0 30 40 50 60 70 80 Temperature (*F) + HFC-245fo with 12 mole Z H20 A HFC-245fo with 71 mole / H20 m HFC-245fa with 47 mole X H20 F IG. 1 W 8.0c) 7.5 A 7.0 A 6.5 , 6.0 30 40 50 60 70 80 Temperature (*F) * Z-FO-1336mzz with 12 mole I H20 A Z-FO-1336mzz with 71 mole Z H20 * Z-FO-1336mzz with 47 mole X H20 F IG. 2
