  • Publication number: 20120149816
    Abstract: A flame retardant thermoplastic resin composition includes (A) about 20 to about 99.49 wt % of an aromatic polyamide resin; (B) 0 to about 50 wt % of a polyphenylene sulfide resin; (C) about 0.5 to about 30 wt % of a phosphinic acid metal salt flame retardant; (D) about 0.01 to about 10 wt % of a zinc compound; and (E) 0 to about 70 wt % of a filler comprising an organic filler, an inorganic filler, or a combination thereof. The flame retardant thermoplastic resin composition can have excellent heat resistance, mechanical strength and processability, a low moisture absorption rate and can inhibit corrosion of a metal surface of an extruder or a mold. The flame retardant thermoplastic resin composition can be used for various electrical electronic parts or auto parts as an environmentally friendly flame retardant thermoplastic resin composition.
