Abstract

[Problem] To provide a thermoplastic elastomer composition that has a low environmental impact and can achieve low compression set. [Solution] The thermoplastic elastomer composition contains (A) recycled ethylene-α-olefin-non-conjugated diene copolymer, (B) a propylene-based polymer, (C) ethylene-α-olefin-non-conjugated diene copolymer (excluding those that fall under (A) recycled ethylene-α-olefin-non-conjugated diene copolymer), (D) a crosslinking agent, and (E) oil, wherein the weight ratio of (E) oil to the total weight of the thermoplastic elastomer composition is 15% by weight to 50% by weight. [Selected Figures] None
