Olefin-based thermoplastic elastomer and molded product produced therefrom |
摘要 |
An olefin-based thermoplastic elastomer comprises a propylene-based resin (A) and an olefin-based copolymer rubber (B), and has a ratio (N1/SS) of first normal stress difference (N1) to shear stress (SS) of 0.6:1 to 1.4:1 said first normal stress difference (N1) and shear stress (SS) being determined by subjecting said elastomer to step shear test at a temperature of 200° C. and a shear rate of 25.1 sec-1. Such olefin-based thermoplastic elastomer shows excellent moldability, transferability of embossed patterns and mechanical strength.
