Abstract
A flame retardant polyamide resin composition includes (A) about 40 to about 60% by weight of a crystalline polyamide resin, (B) about 10 to about 20% by weight of polyphenylene sulfide resin, (C) about 5 to about 15% by weight of flame retardant containing phosphinic acid metal slat compound, (D) about 20 to about 40% by weight of glass fiber and (E) about 0.1 to about 1% by weight of phosphite antioxidant. The flame retardancy polyamide resin composition can have excellent mechanical properties such as impact strength, flexural modulus, flexural strength and/or tensile strength and can exhibit reduced gas blistering on a surface of a specimen thereof.
