PROBLEM TO BE SOLVED: To provide a molding material for gas injection, which realizes lightweight and production strength by gas injection and has good molding appearance and favorable texture.SOLUTION: The polyamide resin composition for gas injection is a polyamide resin composition comprising 8-60 pts.mass glass fiber reinforcement and 0.01-5 pts.mass channel carbon blackbased on 100 pts.mass total of 85-96 pts.mass polyamide 6 resin having a relative viscosity (RV) within the range of 1.8-2.6 when measured at 25°C, 1 g/dl using 96% concentrated sulfuric acid as a solvent and 4-15 pts.mass amorphous polyamide resin. Here, TC2 measured by a differential scanning calorimeter (DSC) is 183-190°C. |
