The present invention relates to a thermoplastic polyurethane composition having a cross-linking site, characterized in that foam can be prepared in a conventional EVA cross-linking foaming system by using a thermoplastic polyurethane having a cross-linking site provided in the molecules of a polyol and a chain extender. Since a thermoplastic polyurethane having a cross-linking site provided in the molecules of a polyol and a chain extender are used, the present invention has a melt viscosity facilitating processing, which is a process of low-temperature processing to which a conventional EVA cross-linking foaming system is applied, at a processing temperature of approximately 130°C or lower, and thus there are effects of having smooth mixing with a cross-linking agent, a foaming agent and various additives, facilitating, by means of the cross-linking site provided in the molecules of a polyol and a chain extender, the formation of foam cells during cross-linking foaming through press molding or injection molding, exhibiting excellent mechanical properties, and enabling foam having various ranges of viscosity according to the amount of a foaming agent to be manufactured.

The present invention provides a thermoplastic polyurethane composition for injection molding and a method of manufacturing the same. The thermoplastic polyurethane composition for injection molding can be easily injection-molded since a slip property is imparted to a soft segment, and can possess excellent durability properties such as heat-aging resistance, photoaging resistance, and wear resistance, and stability properties such as airbag deployment performance and anti-fogging property, as well as excellent tactile sensation and embossing quality, when a chain extender and a multifunctional polydimethylsiloxane-based compound are mixed with an isocyanate- and ether-containing polyester polyol, and can be useful in simplifying processes, reducing manufacturing costs, and simplifying facilities due to a decrease in the number of parts when molded articles are manufactured using the composition.
