Abstract
A flame retarded thermoplastic resin composition comprising (R) a thermoplastic resin comprising (A) a polycarbonate resin and (B) an aromatic polyester resin in an (A)/(B) ratio of 99/1 to 50/50 by weight, and per 100 parts by weight of the thermoplastic resin (R), (C) 0.5 to 100 parts by weight of a silicate compound and (D) 0.5 to 30 parts by weight of an organic phosphorus based flame retarder. The composition can exhibit excellent flame resistance and anti-drip property without containing a halogen atom and, moreover, has excellent properties such as heat resistance, mechanical strength, solvent resistance, surface property of moldings, and dimensional stability.
