ABSTRACT:
There is disclosed a polycarbonate resin composition which comprises an (A) polycarbonate-polyorganosiloxane copolymer, a (B) polycarbonate resin and a (C) polytetrafluoroethylene which has fibril forming capability and an average molecular weight of at least 500,000 wherein the amount of the polyorganosiloxane moiety contained in the component (A) is 0.1 to 2.0% by weight based on the total amount of the components (A) and (B). The resin composition is excellent in flame retardancy, thermal stability and fluidity while preventing melt dripping at the time of combustion. Accordingly, the resin composition is favorably used in the application field of office automation machinery and equipment, electric and/or electronic field, etc.
