THERMOPLASTIC RESIN COMPOSITION AND ARTICLE COMPRISING THE SAME

摘要

PURPOSE: A thermoplastic resin composition is provided to have excellent shock resistance, high stiffness, a high outer tube, and low density by including polyamide resin and glass fiber. CONSTITUTION: A thermoplastic resin composition comprises thermoplastic resin of 10-50 weight%, glass fiber of 31-75 weight%, and a hollow glass microsphere of 15-50 weight%. The thermoplastic resin comprises a mixture which is made of polyamide group resin of 20-95 weight% and denaturalization polyamide group resin of 5-80 weight%. The glass fiber has a flat shape. The ratio of a long shaft of the glass fiber for a short shaft is 1.5-8. The hollow glass microsphere has the average particle diameter of 5-200 micron and specific gravity of 0.05-1.2 g / cc.
