Thermoplastic Resin Composition and Molded Article Prepared Therefrom

Abstract

A thermoplastic resin composition of the present invention comprises: about 100 parts by weight of a polypropylene resin; about 30 to about 45 parts by weight of glass fibers surface-treated with polyolefin; about 50 to about 60 parts by weight of a phosphorus-nitrogen-based flame retardant comprising about 70 to about 90 percent by weight of piperazine pyrophosphate and about 10 to about 30 percent by weight of melamine polyphosphate; and about 1.5 to about 4.5 parts by weight of maleic anhydride-modified polypropylene. The thermoplastic resin composition has excellent flame retardancy (thin film flame retardancy and electrical flame retardancy), impact resistance, rigidity, extrudability, balance of the physical properties, and the like.
