TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The amount of carbon dioxide contained in blowing gas is 50 vol% or more, preferably 70 vol.% or more. The reaction mixture comprises physical blowing agent (less than 50% of total blowing gas volume, preferably less than 30%).    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The dipolar aprotic organic solvent is chosen from dialkyl sulfoxide, N,N-dialkylalkanoamide, phosphonate, tetramethylenesulfone, 1-methyl-2-pyrrolidinone, trialkyl phosphate, acetonitrile, organic carbonate, and their mixtures. Dialkyl sulfoxide is dimethyl sulfoxide, diethyl sulfoxide or diisobutyl sulfoxide. N,N-dialkylalkanoamide is N,N-dimethylformamide, N,N-dimethylacetamide or N,N-diethylacetamide. Phosphonate is O,O-dimethyl, O,O-diethyl, O,O-diisopropyl methylphosphonate or O,O-di(2-chloroethyl) vinylphosphonate. Trialkyl phosphate is trimethyl or triethyl phosphate. The organic carbonate is dimethyl carbonate, ethylene carbonate or propylene carbonate. The amount of aprotic solvent is 2-8 wt.% with respect to total weight of foam-forming mixture.Preferred Agent: The physical blowing agent is chosen from acetone, ethyl acetate, halogenated alkane, butane, hexane, heptane, diethyl ether, pentane and their mixture. Halogenated alkane is chosen from methylene chloride, chloroform, ethylidene chloride, vinylidene chloride, monofluorotrichloromethane, chlorodifluoromethane, dichlorodifluoromethane, trichlorotrifluoroethane, hydrochlorofluorocarbon compound, hydrofluorocarbon compound, and their mixtures.    TECHNOLOGY FOCUS - POLYMERS - Preferred Compound: The polyisocyanate is chosen from aromatic polyisocyanate, aliphatic polyisocyanate, araliphatic polyisocyanate and cycloaliphatic polyisocyanate. The polyurethane or polyisocyanurate foam-forming reaction mixture comprises polyisocyanate, polyol and a catalyst for polyurethane or polyisocyanurate foam-forming reaction. The polyisocyanate is methylene bis(phenylisocyanate). EXAMPLE - Daltolac R 180 (RTM: sucrose-based polyol) (in weight parts) (80), tris(2-chloropropyl phosphate) (20), Niax catalyst DMBA (RTM: dimethyl benzylamine catalyst) (2.2), Niax catalyst A1 (RTM: bis(dimethyl amino ethyl ether catalyst)) (0.2), water (4), Niax silicone SR 321 (RTM: silicone) (2), and Suprasec DNR (RTM: polymeric methylene diisocyanate) (155) were mixed to obtain polyurethane foam forming mixture. A galvanized steel plate was placed in metal mold, and sealed. The obtained mixture was introduced to the mold and mold was placed in oven. The foam was remained in oven for 5 minutes at molding temperature of 35degreesC, and cured foam sandwich panel was obtained. The panel had adhesion of 82.8 KPa.
