PURPOSE: A thermoplastic resin composition is provided, to improve the long-termed heat resistance and the hydrolysis resistance, thereby not allowing the impact resistance to be changed according to the change of the processing temperature of an extruder and enhancing the impact resistance. CONSTITUTION: The thermoplastic resin composition comprises 20-40 wt% of a polycarbonate resin; 10-30 wt% of a polybutylene terephthalate; 10-25 wt% of a polyethylene terephthalate resin; 5-20 wt% of an acrylonitrile-butadiene-styrene resin; and 5-15 wt% of an impact reinforcing agent. Preferably the impact reinforcing agent has a core-cell structure, wherein the core part is selected from the group consisting of a diene elastomer, an ethylene-propylene-diene rubber, an acrylic elastomer and a polyurethane elastomer; and the cell part is selected from methacrylic ester. |
