PURPOSE: Provided is a thermoplastic resin composition excellent in fatigue strength, fluidity, and impact strength, which can be used for electric and electronic parts, parts of cars, and operation parts of electric home appliances. CONSTITUTION: The thermoplastic resin composition comprises: 20-40pts.wt. of a graft copolymer resin comprising 60-90wt% of a graft copolymer resin having an average particle diameter of 0.20-0.40 micrometer and 40-10wt% of a graft copolymer resin having an average particle diameter of 0.1-0.20 micrometer; 60-80pts.wt. of an SAN resin comprising 20-40pts.wt. of an SAN resin having 30-40wt% of acrylonitrile and a weight average molecular weight of 140,000-180,000 and 40-60pts.wt. of an SAN resin having 30-40wt% of the acrylonitrile and a weight average molecular weight of 70,000-120,000; 0.2-0.6pts.wt. of a metal lubricant such as calcium stearate, barium stearate, magnesium stearate; 1.0-2.0pts.wt. of an inside lubricant such as polyethylene wax or ethylene bis stearoamide. |
