14 Claims

1. A thermoplastic polyamide resin composition comprising:

a polyamide resin;

an olefinic rubber;

polyethylene; and

a nucleating agent comprising aromatic polyamide and a heat-dissipation filler,

wherein the polyamide resin comprises polyamide 66 and polyamide 6,

wherein the aromatic polyamide is prepared by condensation polymerization between an aromatic dicarboxylic acid and a diamine monomer,

wherein the polyamide resin composition comprises an amount of about 78% to 90% by weight of the polyamide resin, an amount of about 5% to 12% by weight of the olefinic rubber, an amount of about 3% to 8% by weight of the polyethylene and an amount of about 1% to 2% by weight of the nucleating agent, the % by weight based on the total weight of the polyamide resin composition,

wherein the thermoplastic polyamide resin composition comprises an amount of about 0.5% to 1.0% by weight of the aromatic polyamide and an amount of about 0.5% to 1.0% by weight of the heat-dissipation filler, the % by weight based on the total weight of the polyamide resin composition.
