Zusammenfassung:	Disclosed herein are improved thermoplastic polyurethane compositions, articles, and related methods. These compositions include aliphatic thermoplastic polyurethanes having a hard segment content ranging from 57 percent to 80 percent by weight. The hard coat compositions have a Shore D hardness of at least 70 and can display an Elongation at Break test result at 25 degrees Celsius of at least 150 percent. These materials, when hardened, can serve decorative and/or protective functions while displaying both a high degree of elongation at moderate temperatures and high hardness. En la presente descripción se describen composiciones de poliuretano termoplástico mejoradas, artículos, y métodos relacionados. Estas composiciones incluyen poliuretanos termoplásticos alifáticos que tienen un contenido de segmentos duros que varía de 57 por ciento a 80 por ciento en peso. Las composiciones de revestimiento duro tienen una dureza Shore D de al menos 70 y pueden mostrar un resultado de la prueba de alargamiento en el punto de ruptura a 25 grados Celsius de al menos 150 por ciento. Estos materiales, cuando se endurecen, pueden servir para funciones decorativas y/o de protección, que muestran tanto un grado alto de alargamiento a temperaturas moderadas como alta dureza.
