Estimating the term…
A polybutylene terephthalate resin composition is provided, which exhibits an excellent impact resistance, flame retardancy, heat aging resistance, lightfastness, and moist heat resistance and which also has an excellent moldability. Also provided is a molded article formed by molding this polybutylene terephthalate resin composition. The polybutylene terephthalate resin composition contains a polybutylene terephthalate resin (A) and a polycarbonate resin (B), and contains 50 to 80 mass parts (A) and 20 to 50 mass parts (B) per 100 mass parts of the total of (A) and (B), and additionally contains, per 100 mass parts of the total of (A) and (B), 5 to 20 mass parts of an elastomer (C), 5 to 40 mass parts of a flame retardant (D), and 1 to 15 mass parts of an antimony compound (E).
A polybutylene terephthalate resin composition comprising a 50 to 80 mass parts of a polybutylene terephthalate resin (A) and 20 to 50 mass parts of a polycarbonate resin (B) per 100 mass parts of the total of (A) and (B), and further comprising, per 100 mass parts of the total of (A) and (B), 5 to 20 mass parts of an elastomer (C), 5 to 40 mass parts of a flame retardant (D), 1 to 15 mass parts of an antimony compound (E), and 0.5 to 10 mass pans of a titanium oxide (F) that has been subjected to a surface treatment with an alumina compound and an organosiloxane compound, wherein the elastomer (C) is an acrylic core/shell graft copolymer in which both the core and shell are an acrylate ester.
