| 摘要 |
The present invention relates to a polypropylene resin composition, more particularly to a composition comprising an ethylene/propylene block copolymer, an ethylene/alpha-olefin copolymer rubber, a styrene-based polymer rubber, a polypropylene-silicone rubber master batch, a magnesium compound and an inorganic filler. The polypropylene resin composition of the present invention exhibits superior rigidity, scratch resistance and glossiness, outstanding laser processability and low-temperature impact resistance, and also superior fluidity. Therefore, it is applicable to manufacture interior materials of a vehicle such as an instrument panel. Especially, the present invention is suitable to manufacture an air bag deployable instrument panel assembly requiring no coating.
