Thermoplastic resin composition and article produced therefrom

A thermoplastic resin composition comprising:

• 100 parts by weight of a polycarbonate resin;
• 5 to 20 parts by weight of a rubber modified aromatic vinyl copolymer resin;
• 0.5 to 3 parts by weight of a maleic anhydride-grafted rubber polymer;
• 50 to 100 parts by weight of glass fibers;
• 10 to 30 parts by weight of barium sulfate;
• and
• 5 to 20 parts by weight of a phosphorus flame retardant,
• wherein the glass fibers and the barium sulfate are present in a weight ratio of 3:1 to 5:1, and
• wherein the thermoplastic resin composition has:
• a notched Izod impact strength of 10 kgf·cm/cm to 20 kgf·cm/cm, as measured on a ⅛″ thick specimen in accordance with ASTM D256;
• a yellow index difference (ΔYI) of 1 to 5, as measured on an injection molded specimen having a size of 50 mm×90 mm×3 mm in accordance with Equation 1:
• ΔYI=YI1−YI0 [Equation 1]
• where YI0 is an initial yellow index of the specimen of the thermoplastic resin composition and YI1 is a yellow index of the specimen measured after exposure under conditions of 85° C. and 85% RH for 500 hours;
• a flame retardancy of V-1 or higher, as measured on a 3 mm thick specimen in accordance with UL-94;
• a melt-flow index (MI) of 30 g/10 min to 45 g/10 min, as measured under conditions of 250° C. and 10 kgf in accordance with ASTM D1238, and
• a specific gravity of 1.55 to 1.65, as measured at 23° C. in accordance with ASTM D792 A.
