  • Patent number: 10556982
    Abstract: A thermoplastic polyurethane resin composition having enhanced texture and durability is capable of ensuring excellent appearance quality by applying polyester polyol including, polytetramethylene ether glycol and polydimethylsiloxane diol to an existing thermoplastic polyurethane resin composition, having excellent mechanical properties and long-term durability, such as anti-scratch and abrasion resistance, while largely enhancing texture quality, largely reducing producing costs by replacing a material such as natural leather, reducing generation of a volatile organic compound (VOC), and using the VOC in a surface material for a vehicle interior material.

  • 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.
