Abstract
A polycarbonate resin composition includes (A) about 90 to about 97% by weight of a rubber-reinforced polystyrene resin, (B) about 3 to about 10% by weight of a polyphenylene ether resin, (C) about 10 to about 20 parts by weight of a halogen compound including a triazine group, or a mixture of a halogen compound including a triazine group and a diphenyl ethane bromide compound based on about 100 parts by weight of a base resin comprising (A) and (B), and (D) about 0.01 to about 3 parts by weight of an antimony compound based on about 100 parts by weight of the base resin comprising (A) and (B). The composition can exhibit excellent flame retardancy, colorability and injection molding thermal stability.
