摘要： The thermoplastic polyurethane molding of the present invention is obtained by melting, molding, cooling and solidifying, subsequently heating to a temperature T1 (specifically, 180 to 190° C) that is not more than flow starting temperature Tm and not less than glass transition point Tg and cooling down quickly to a temperature T2 (Tm>T1>T2>Tg, specifically, 160 to 165° C.). In dynamic viscoelasticity measurement, the difference between the temperature at which LogE′ turns 4.5 MPa and the peak temperature of tan δ is 190 to 225° C.
