Title:
NON-BLOOMING THERMOPLASTIC POLYURETHANE COMPOUNDS AND THERMOPLASTIC ARTICLES MOLDED THEREFROM
Document Type and Number:
WIPO Patent Application WO/2020/024242
Kind Code:
A1
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.
