Abstract
A flameproof thermoplastic resin composition comprises (A) 100 parts by weight of a thermoplastic resin; (B) about 1 to about 40 parts by weight of a sublimational filler; and (C) about 1 to about 30 parts by weight of a flame retardant. The thermoplastic resin composition can solve the problems of high specific gravity and deterioration of flame retardancy caused by adding a conventional filler.
