PURPOSE:To improve the flame retardancy, rigidity, impact resistance and flowability by incorporating an inorganic filler and a specified composite rubber into a resin composition consisting of an aromatic polycarbonate, a specified thermoplastic graft copolymer, a phosphoric ester and polytetrafluoroethylene. CONSTITUTION:100 pts.wt. resin composition consisting of 45-90wt.% aromatic polycarbonate, 10-40wt.% thermoplastic graft copolymer obtained by grafting a diene rubber component with a vinyl cyanide compound and an aromatic vinyl compound, 3-12wt.% phosphoric ester (e.g. triphenyl phosphate) and 0.1-2wt.% polytetrafluoroethylene is mixed with 5-25 pts.wt. scaly inorganic filler (e.g. talc) and 1-13 pts.wt. composite rubber having a network tructure wherein a polyorganosiloxane rubber component and a polyalkyl (meth)acrylate rubber component penetrate into each other. |
