<P>PROBLEM TO BE SOLVED: To provide a thermoplastic elastomer composition that provides little load on the environment and has superior mechanical characteristics. <P>SOLUTION: The thermoplastic elastomer composition is obtained by melt-kneading 10-90 pts.wt of ethylene-α-olefin-based copolymer rubber (A), 1-50 pts.wt of a non-petroleum raw material-derived thermoplastic resin (B), 1-50 pts.wt of a modified propylene-based copolymer (C), 1-50 pts.wt of a propylene-based polymer (D), 0.001-5 pts.wt of a crosslinking agent (E), and 0-50 pts.wt of a mineral oil-based softener (F), wherein the addition amounts of the components (A), (B), (C), (D) and (F) are addition amounts when the total amount of the components (A), (B), (C), (D) and (F) is considered to be 100 pts.wt, and the addition amount of the component (E) is an addition amount to 100 pts.wt of the total amount of the components (A), (B), (C), (D) and (F). <P>COPYRIGHT: (C)2013,JPO&INPIT |
