Abstract
A thermoplastic resin composition includes: about 100 parts by weight of a thermoplastic resin including about 35 wt % to about 55 wt % of a polycarbonate resin, about 3 wt % to about 9 wt % of a first rubber-modified aromatic vinyl graft copolymer, about 7 wt % to about 13 wt % of a second rubber-modified aromatic vinyl graft copolymer, and about 30 wt % to about 50 wt % of an aromatic vinyl copolymer resin; about 6 to about 13 parts by weight of a halogen compound; and about 8 to about 17 parts by weight of a phosphoric ester compound. The first rubber-modified aromatic vinyl graft copolymer is obtained by graft copolymerization of an alkyl(meth)acrylate, an aromatic vinyl monomer and a copolymerizable monomer to a rubber polymer, and the second rubber-modified aromatic vinyl graft copolymer is obtained by graft copolymerization of an aromatic vinyl monomer and a copolymerizable monomer to a rubber polymer.
