Abstract
There is dsiclosed a flame retardant resin composition comprising the following components (A), (B), (C), (D), (E) and (F), wherein 1-10 parts by weight of (C), 2-10 parts by weight of (D), 0.05-2 parts by weight of (E) and 0.01-10 parts by weight of (F) are contained per 100 parts by weight of a resin whose weight ratio of (A)/(B) is 75/25-90/10. PA1 (A) a polycarbonate resin whose viscosity-average molecular weight is 16,000-29,000, PA1 (B) a polyalkylene terephthalate resin, PA1 (C) a copolymer containing a rubbery polymer and at least one selected from the group consisting of aromatic vinyl monomers, vinyl cyanide monomers, acrylic acid, acrylic esters, methacrylic acid, methacrylic esters and maleimide-type monomers as components, PA1 (D) an organic phosphorus-type flame retardant, PA1 (E) a fluorocarbon-type resin, and PA1 (F) an epoxy compound not containing halogens. The flame retardant resin composition is halogen-free and possesses well-balanced properties of flame retardancy, impact strength, heat resistance, moldability, chemical resistance and heat-induced discoloration resistance, and is improved in silver streaks formation.
