Abstract
According to the present invention, there are provided a polycarbonate resin composition which comprises (A) 40 to 92 wt % of an aromatic polycarbonate resin (component “a”), (B) 5 to 40 wt % of a styrene-based resin (component “b”), (C) 3 to 20 wt % of a phosphate-based flame retardant (component “c”), and (D) 0.1 to 30 parts by weight of a silicate filler (component “d”) based on 100 parts by weight of the total of the components “a”, “b” and “c”, and which has a chlorine compound content in terms of chlorine atoms of 100 ppm or less as well as a molded product thereof. The resin composition of the present invention can provide a molded product having excellent resistance to wet heat and flame retardancy.
