The present invention relates to a polyester resin composition excellent in flame retardancy and heat resistance, 50 to 78% by weight of polyester resin, 5 to 10% by weight of phosphinate or diphosphinate, 1 to 5% by weight of nitrogen-based flame retardant, It is related with the polyester resin composition containing 1-3 weight% of aramid flame retardants and 15-30 weight% of inorganic fillers. The polyester resin composition according to the present invention can be suitably used as a material for automobile and electric and electronic parts requiring high heat and flame retardant properties by improving mechanical rigidity and heat resistance, surface gloss and processability as well as environmentally friendly flame retardancy. |
