  • Patent number: 9855688
    Abstract: 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.
