The present invention relates to a polyester-based resin composition and a molded article manufactured using the same. More particularly, the present invention relates to a polyester-based resin composition including 93 to 99.5% by weight of a polybutylene terephthalate resin; 0.1 to 3% by weight of a polar group-containing lubricant; and 0.1 to 2% by weight of an antioxidant and a molded article manufactured using the polyester-based resin composition.According to the present invention, a polyester-based resin composition having excellent fluidity, mechanical properties, thermal stability, injection stability, and surface properties and a molded article manufactured using the same may be provided. In particular, due to excellent surface properties thereof, the polyester-based resin composition does not exhibit iridescence caused by diffuse reflection. In addition, the polyester-based resin composition has a low haze value. Accordingly, the polyester-based resin composition may be used to manufacture a molded article such as an automotive headlamp bezel.
本发明涉及一种聚酯类树脂组合物和使用该聚酯类树脂组合物制造的模制品。更具体地,本发明涉及一种聚酯类树脂组合物和使用该聚酯类树脂组合物制造的模制品,所述聚酯类树脂组合物包含:93重量%至99.5重量%的聚对苯二甲酸丁二醇酯树脂;0.1重量%至3重量%的含极性基团的润滑剂;和0.1重量%至2重量%的抗氧化剂。根据本发明,可以提供一种具有优异的流动性、机械性能、热稳定性、注射稳定性和表面性能的聚酯类树脂组合物和使用该聚酯类树脂组合物制造的模制品。具体地,由于其优异的表面性能,所述聚酯类树脂组合物不表现出由漫反射引起的彩虹色。此外,所述聚酯类树脂组合物具有低的雾度值。因此,所述聚酯类树脂组合物可以用于制造模制品,如汽车前照灯边框。
