Laser-weldable flame-retardant polyester resin composition and molded article containing same

Abstract

The present invention relates to a laser-weldable flame-retardant polyester resin composition and a molded article containing same and, more specifically, to a polyester resin composition and a molded article comprising same, wherein the polyester resin composition contains polybutylene terephthalate (PBT) and polyethylene terephthalate (PET) at a specific mixing weight ratio and further contains polycarbonate (PC), a polysiloxane-polycarbonate (Si-PC) copolymer, or a mixture thereof, and a flame retardant, and thus exhibits superb laser weldability due to a high laser transmittance and a small deviation in transmittance according to the injection condition, as well as excellent mechanical characteristics and flame retardancy.
