Abstract:
A thermoplastic elastomer composition contains components (A), (B), (C), and (D), wherein the weight ratio of component (C) to component (D) is ≥0.1 and <2, component (A) is an ethylene random copolymer containing ≥50% and ≤90% of a monomer unit derived from ethylene by weight relative to the component (A) and a monomer unit derived from at least one monomer selected from the group consisting of α-olefins having a number of carbon atoms of ≥3 and ≤10, component (B) is a polymer containing >50% and ≤100% of a monomer unit derived from propylene by weight relative to the component (B), component (C) is a copolymer containing an ethylene polymerization block and an ethylene-α-olefin copolymerization block, and component (D) is an ethylene polymer containing >90% and ≤100% of a monomer unit derived from ethylene by weight relative to the component (D).
