THERMOPLASTIC URETHANE RESIN

摘要

An object is to provide a material for slush molding that is excellent in low-temperature meltability, and gives a molded body excellent in both of tensile strength and elongation. The present invention is a thermoplastic urethane resin (D) for thermal molding, which is a thermoplastic urethane resin yielded by causing high molecular weight diols (A) to react with a diisocyanate (B), wherein the high molecular weight diols (A) comprise a polyester diol (A1) having a glass transition temperature of 0 to 70°C, and a high molecular weight diol (A2) having a solubility parameter lower than that of the (A1) by 1.2 to 3.0 and further having a glass transition temperature of -40 to -75°C.
