  • Patent number: 11732126
    Abstract: A thermoplastic resin composition of the present invention comprises: about 100 parts by weight of a thermoplastic resin including a polyester resin; about 50-150 parts by weight of glass fibers; and about 1-10 parts by weight of a polyether-ester copolymer, wherein the polyether-ester copolymer has a melt volume flow rate (MVR) of about 30-120 cm3/10 min as measured under conditions of 230° C. and 2.16 kg based on ISO 1133. The thermoplastic resin composition is excellent in impact resistance, appearance characteristics, metal joining properties, and the like.
