The present invention relates to a thermoplastic polyurethane composition with crosslinking sites, which uses a thermoplastic polyurethane having crosslinking sites imparted in the molecules of polyols and chain extenders and thus can be used to form a foam in a conventional EVA crosslinking foaming system. By using the thermoplastic polyurethane having crosslinking sites imparted in polyol and chain extender molecules, the composition of the present invention possesses a melt viscosity that can be easily processed at a processing temperature of 130°C or less in a low-temperature foaming process to which a pre-existing EVA crosslinking foaming system is applied, and thus can be easily mixed with a crosslinking agent, a foaming agent and other additives. Also, when performing a crosslinking foaming through press molding or injection molding, the composition of the present invention, due to the crosslinking sites imparted in the molecules of polyols and chain extenders, can form a foam which ...
