    • PURPOSE: A polypropylene resin composition is provided to have excellent rigidity and impact strength, to have excellent moldability, and to remarkably reduce flow marks. CONSTITUTION: A polypropylene resin composition comprises 45-90 wt% of a xylene-soluble part and a propylene homopolymer with a melt index of 25-100 g/10 minutes (230 °C); 5-50 wt% of a blend of two or more ethylene-alpha-olefin-based random copolymers having different inherent viscosities from each other; and 5-50 wt% of an inorganic filler. The polydispersity index of the propylene-based block copolymer is 5-12, and the stereoregularity thereof by a pentad method is 94% or more.

    • PURPOSE: A polypropylene resin composition is provided to secure the mold ability during an extruding process, and to improve the shock resistance and the rigidity of the resin composition for applying the composition for an interior and exterior decorative material of a vehicle. CONSTITUTION: A polypropylene resin composition contains 45~90wt% of propylene-based block copolymer, 5~30wt% of ethylene/alpha-olefin random copolymer elastomor, and 5~25wt% of inorganic filler. The melting index of the polypropylene resin composition is 40~150 g/10 minutes. The propylene-based block copolymer is formed with a propylene homopolymer part, and a propylene-ethylene random copolymerization part.
