PURPOSE: A polyamide resin composition is provided to have excellent balance of physical properties of mechanical property, heat resistance and dimensional stability, thereby capable of being used for various molded products, especially for plastic exterior products like electric and electronic components, UTH(under the hood) of vehicles, etc. CONSTITUTION: A polyamide resin composition comprises 20-80 weight% of crystalline polyamide mixed resin, 1-30 weight% of non-crystalline polyamide resin comprising an aromatic group, and 10-50 weight% of glass fiber. The crystalline polyamide mixed resin comprises a first crystalline polyamide resin comprising an (A-1) aliphatic group, and a second crystalline polyamide resin comprising an (A-2) aliphatic group. The weight ratio of the first crystalline polyamide resin and the second crystalline polyamide resin are 1:3-3:1. |
