    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: 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 and 0.1 to 5 parts by weight of urea, and a catalyst with a polyisocyanate compound and foaming the mixture. According to the process, there can be produced a polyurethane foam which satisfies both productivity and moldability even when having a low density, and is suitable for use in shoe soles.

    Abstract: PROBLEM TO BE SOLVED: To scarcely bring about a fault for lowering surface properties of a molding such as a void or an air shortage or an insufficiency in filling when molded by providing specific number or more of discharge holes each having a specific hole size and molding by using a foaming machine having a nozzle portion having the holes of both ends at a specific distance. SOLUTION: A foaming machine having a nozzle portion 1 including three or more discharge holes 2 each having a hole size of 1 to 8 mm so that a distance W between the holes of both ends of 30 to 100 mm is used. The shape of the portion 1 is a shape for uniformly filling a liquid-like molding material supplied from a liquid-like molding material supply hole 3 in the portion 1. The hole sizes of the holes 2 may be the same or different. The portion 1 can be disassembled to facilitate cleaning therein and its material can manufacture a desired foamed molding. Thus, the foamed molding for scarcely bringing about a fault for lowering surface properties of a molding such as a void or an air shortage or an insufficiency in filling when molded can be manufactured.
