Abstract: A process for producing a polyurethane foam which comprises mixing a polyol solution comprising 100 parts by weight of a polyester polyol, 0.1 to 1.8 parts by weight of water, 0.1 to 5 parts by weight of urea, and a catalyst with a polyisocyanate compound and foaming the mixture. By the production process, a polyurethane foam can be produced which can combine productivity with moldability even when having a low density and is suitable for use in shoe soles.

Abstract: A polyester-polyol being liquid at 40° C. and having a viscosity of not more than 10,000 mPa.s at 60° C., prepared by polycondensation of an acid component including at least one phthalic acid component selected from phthalic anhydride and o-phthalic acid, and an aliphatic polybasic acid, with a polyhydric alcohol; a process for preparing a polyurethane foam including reacting a polyisocyanate component with a polyol component including the polyester-polyol; a process for preparing an isocyanate prepolymer from a polyisocyanate component and a polyol component including the polyester-polyol; and a process for preparing a polyurethane foam including reacting an isocyanate prepolymer prepared from a polyisocyanate component and a polyol component including the polyester-polyol, with a polyol component. The resulting polyurethane foam shows remarkably improved physical properties such as tensile strength and tear strength, while having low density, acceptable appearance and texture.

Abstract: The use of pulverized coal as the fuel to be injected into a metallurgical or combustion furnace becomes possible enabled by improving the transportability thereof. Further, a pulverized coal is provided, which is inhibited from bridging or channelling in a hopper, or piping choking. A water-soluble inorganic salt having a polar group is made to adhere to pulverized coal which is prepared from raw coal having an average HGI of 30 or above and which is in a dry state at the injection port of a metallurgical or combustion furnace, the inorganic salt being selected from among BaCl2, CaCl2, Ca(NO2)2, Ca(NO3)2, Ca(ClO)2, K2CO3, KCl, MgCl2, MgSO4, NH4BF4, NH4Cl, (NH4 ) 2SO4, Na2CO3, NaCl, NaClO3, NaNO2, NaNO3, NaOH, Na2S2O3, NaS2O5, HNO3, H2SO4, H2CO3, and HCl.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a polyurethane foam scarcely causing disadvantages of lowering surface properties of a molded product such as pinholes on the surface, and to obtain a mold release agent for producing the polyurethane foam suitably usable in the method.
SOLUTION: The mold release agent for producing polyurethane foam comprises (A) one or more kinds of nitrogen-containing compounds selected from the group consisting of an amine and an organic ammonium salt and (B) a silicone compound. The method for producing the polyurethane foam molded product is characterized by using the mold release agent for producing the polyurethane foam.
