PURPOSE:To provide a polybutylene terephthalate (PBT) resin composition which has excellent mechanical strength, flame retardancy and the fluidity at the molten state with reduced flashing. CONSTITUTION:A resin mainly comprising PBT is combined with 2 to 25wt.% of a brominated epoxy flame retardant, 2 to 15wt.% of antimony tri- or pentoxide auxiliary flame retarder, 0.05 to 5 wt.% of polytetrafluoroethylene resin prepared by emulsion polymerization and 0 to 60wt.% of an inorganic filler based on the total composition to give the objective composition. |
