Abstract
The present invention provides a thermoplastic elastomer composition for foaming. The thermoplastic elastomer composition comprises: (A) an ethylene-based copolymer; (B) an olefin block copolymer; (C) an unsaturated aliphatic rubber; and (D) a crosslinking agent. The olefin block copolymer is different from the ethylene-based copolymer. The weight ratio of the unsaturated aliphatic rubber (C) to the olefin block copolymer (B) is 1:1.5 to 1:5.
