Abstract:
The present invention relates to a thermoplastic elastomer composition comprising 10 to 80 parts by mass of polyolefin resin (A), 10 to 80 parts by mass of styrene-based thermoplastic elastomer (B), and 1 to 20 parts by mass of at least partially crosslinked rubber (C) (with the total amount of the components (A), (B) and (C) being 100 parts by mass), wherein the composition has a type D hardness (i.e., the instantaneous value) of 35 or more and 70 or less in accordance with JIS K6253, and relates to a molded thermoplastic elastomer product obtained by molding the composition.
