Publication number: 20100144939Abstract: A flame retardant polycarbonate resin composition comprising 100 parts by weight of a polycarbonate resin (A), 0.01 to 3 parts by weight of silsesquioxane (B), 0.005 to 1.0 part by weight of an organic metal salt compound (C) and 0.01 to 3 parts by weight of a fibril-forming type fluorinated polymer (D), wherein said silsesquioxane (B) is characterized by a specific structure (a triangular cone shape). The flame retardant polycarbonate resin composition of the present invention can achieve a high degree of flame retardance even in thin-walled molded products without generating a gas containing chlorine or bromine during combustion originating from a chlorine type or bromine type flame retardant since said flame retardant is not used. Therefore, the flame retardant polycarbonate resin composition of the present invention can ideally be used in housings and parts for electrical, electronic, ITE and the like products, and its industrial utility value is extremely high.Type: ApplicationFiled: March 19, 2007Publication date: June 10, 2010Inventors: Koji Okada, Claude Van Nuffel
