<p>Provided are: a thermoplastic elastomer composition which exhibits excellent fluidity in molding, mechanical properties, surface appearance, touch, and wear resistance; and molded articles thereof. A thermoplastic elastomer composition which is obtained by crosslinking a composition that comprises (A) 100 parts by mass of a polypropylene resin, (B) 80 to 200 parts by mass of a product of hydrogenation of a block copolymer comprising at least one block composed of conjugated diene monomer units and at least one block composed of aromatic vinyl monomer units, (C) 100 to 250 parts by mass of a softener, and (D) 5 to 20 parts by mass of a polyorganosiloxane, and which satisfies the requirements (1) to (5): (1) the content of the aromatic vinyl monomer units in the component (B) is 30 to 80% by mass; (2) the melt flow rate is 35 to 85g/10min; (3) the JIS A hardness is 60 to 90; (4) the compression set is 30 to 70%; and (5) the tensile elongation at -30°C is 80% or more.</p> |
