Thermoplastic elastomer resin composition with improved fluidity and molded article produced therefrom

A thermoplastic elastomer resin composition comprising:

• an amount of about 10% to 60% by weight of styrene-based synthetic rubber having a melt index in a range of 30 g/10 min to 100 g/10 min which is measure at a temperature of 190° C. and a load of 2.16 kg;
• an amount of about 12% to 30% by weight of a propylene-ethylene copolymer having a melt index in a range of 60 g/10 min to 150 g/10 min which is measured at a temperature of 230° C. and a load of 2.16 kg;
• an amount of about 10% to 50% by weight of cross-linked rubber;
• an amount of about 1% to 10% by weight of oil;
• an amount of about 1% to 5% by weight of an inorganic filler;
• and
• an amount of about 0.1% to 5% by weight of a lubricant,
• wherein the % by weight is based on the total weight of the thermoplastic elastomer resin composition, and
• wherein the cross-linked rubber is obtained by cross-linking an ethylene-propylene-diene monomer with a polypropylene resin.
