Abstract: Thermoplastic articles are molded from thermoplastic polyurethane compounds including blends of aromatic polycaprolactone thermoplastic polyurethane and other aromatic thermoplastic polyurethane selected from aromatic polyester thermoplastic polyurethane, aromatic polyether thermoplastic, and combinations thereof. The thermoplastic articles exhibit enhanced stain resistance, as represented by achieving a rating of 2 or better according to Blue Jean Abrasion Test, relative to thermoplastic articles molded from thermoplastic polyurethane compounds including either aromatic polyester thermoplastic polyurethane or aromatic polyether thermoplastic only, 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.

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.

Abstract: Thermoplastic elastomer compounds include (a) at least about 40 weight percent of thermoplastic polyurethane selected from polycaprolactone-type thermoplastic polyurethane, polyether-type thermoplastic polyurethane, and combinations thereof, and (b) at most about 5 weight percent of polysiloxane. The thermoplastic elastomer compounds can be molded into thermoplastic articles which exhibit substantially no blooming after weathering, while also exhibiting good processability, useful functionality, and desirable aesthetics. The thermoplastic compounds can be especially useful for making overmolded thermoplastic articles.
