摘要：
There is provided a thermoplastic elastomer composition, comprising per 100 parts by weight of ethylene-propylene-diene monomer (EPDM), 20 to 30 parts by weight of polypropylene (PP), 7 to 30 parts by weight of ethylene octene rubber (EOR), 7 to 23 parts by weight of propylene butene rubber (PBR), and 55 to 65 parts by weight of mineral oil, wherein a content of said poly(1-butene) (PB) is small parts by weight. Thereby, there can be provided a thermoplastic elastomer composition and a molded member obtained by molding the same, which can be superior in the shape recovery property at the deformation, without deteriorating the tactile quality, gloss-change resistance, or formability of particles.
