Abstract:
Thermoplastic articles are molded from thermoplastic polyurethane compounds including aromatic polycaprolactone thermoplastic polyurethane. The thermoplastic articles exhibit enhanced stain resistance, as represented by achieving a rating of 1 according to Blue Jean Abrasion Test, relative to thermoplastic articles molded from thermoplastic polyurethane compounds including other types of thermoplastic polyurethanes, while also having good clarity (i.e., low haze) and other desirable properties. The thermoplastic articles can be especially useful as protective cases for handheld electronic devices.
