PURPOSE: A polypropylene resin composition is provided to provide an excellent surface property less damaged by friction, impact, etc, and to able to manufacture a vehicle interior/exterior by only extrusion process without separate anti-scratch process. CONSTITUTION: A polypropylene resin composition comprises a crystalline olefin-based resin which is a single material or a mixture selected from isotactic polypropylene and an alpha-olefin-propylene copolymer, a polyolefin-based elastomer, talc, and needle-type calcium metasilicate filler. A comprised amount of the needle-type calcium metasilicate filler is 3-30 parts by weight based on the polypropylene resin composition. A comprised amount of the crystalline olefin-based resin is 40-95 parts by weight. |
