Flame retardant resin composition and molded article thereof

摘要

Disclosed are a flame retardant resin composition which comprises (A) 70 to 98.5% by weight of a propylene- alpha -olefin block copolymer wherein a ratio ( eta 1/ eta 2) of melt viscosity eta 1 at a shear rate of 10<1> sec<-1> to melt viscosity eta 2 at a shear rate of 10<2>sec<-1> is 3.5 to 8 as measured as by a slit die method, (B) 1 to 20% by weight of an organic bromine type flame retardant, and (C) 0.5 to 10% by weight of antimony oxide, wherein the total percentage of (A) + (B) + (C) is equal to 100% by weight and a molded article thereof.
