Disclosed are a thermoplastic elastomer resin composition, and a molded article produced therefrom. The thermoplastic elastomer resin composition includes styrene-based synthetic rubber having a melt index in a range of 30 g/10 min to 100 g/10 min which is measured at a temperature of 190° C. and a load of 2.16 kg, 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, cross-linked rubber, oil, an inorganic filler, and a lubricant in appropriate amounts.

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

The present disclosure provides a thermoplastic resin composition having high rigidity and a low coefficient of linear thermal expansion and a molded article including the same. The thermoplastic resin composition includes a first propylene-ethylene copolymer, a second propylene-ethylene copolymer, a thermoplastic elastomer, an inorganic filler, and a sodium-phosphate-based nucleating agent as appropriate, and thus a molded article produced therefrom can exhibit improved mechanical rigidity, impact resistance, and dimensional stability. Even when formed to a low thickness for weight reduction, the molded article can be imparted with excellent processability, high tensile strength, a high flexural modulus, and high impact strength.
