PURPOSE:To obtain a resin composition giving a molded article having decreased warpage without deteriorating various excellent properties of base resin by compounding a glass-fiber reinforced polybutylene terephthalate with a specific kind of polymer, a flaky inorganic filler and a powdery inorganic filler. CONSTITUTION:The objective composition contains (A) 40-80wt.% of a polymer mixture composed of (A1) 55-95 pts.wt. of polybutylene terephthalate and (A2) 45-5 pts.wt. of one or more polymers selected from styrene polymer, methyl methacrylate polymer and polycarbonate, (B) 3-35wt.% of glass fiber, (C) 5-25wt.% of a flaky inorganic filler preferably having a thickness of 0.5-20mum and an aspect ratio of 10-80, (D) 5-42wt.% of a powdery inorganic filler preferably having a particle diameter of 1-30mum and, as necessary, (E) 3-20wt.% of a bromine-based polymeric flame-retardant and (F) 1-10wt.% of an antimony compound. |
