PROBLEM TO BE SOLVED: To inexpensively obtain both a thermoplastic elastomer composition having excellent flexibility, weather resistance, heat resistance, low-temperature characteristics, strength, moldability and processability and an elastomer member having excellent scratch resistance comprising the composition, not requiring surface coating. SOLUTION: This thermoplastic elastomer composition comprises (A) 100 pts.wt. of polyurethane elastomer and (B) 10-900 pts.wt. of a copolymerized metallocene polyolefin of 10-40 wt.% of a 3-12Cα-olefin comonomer and ethylene, having 0.86-0.94 density and 1.5-5.0 molecular weight distribution (Mw/Mn). |
