  • Thermoplastic resin composition and article produced therefrom
    Patent number: 10745554
    Abstract: Disclosed herein is a thermoplastic resin composition. The thermoplastic resin composition includes: about 100 parts by weight of a polycarbonate resin; about 20 parts by weight to about 130 parts by weight of flat glass fibers coated with an epoxy compound; about 0.5 parts by weight to about 3 parts by weight of a modified polyolefin including a repeat unit represent by Formula 1 and a repeat unit represented by Formula 2; about 5 parts by weight to about 20 parts by weight of a phosphazene compound; and about 0.1 parts by weight to about 5 parts by weight of a fluorinated olefin resin. The thermoplastic resin composition has good properties in terms of impact resistance, rigidity, and/or flame retardancy.
