Abstract:
1. A polypropylene resin composition comprising: a first pellet (A) prepared using a resin composition (A) comprising (a-1) about 22 to about 58 wt % polypropylene resin, wherein said polypropylene resin is selected from the group consisting of polypropylene homopolymer alone or a mixture of polypropylene homopolymer and polypropylene-ethylene copolymers, wherein the polypropylene homopolymer has a pentad ratio (% mmmm) of about 96% or higher, and a limiting viscosity of about 0.7 to about 2.5 dl/g and the polypropylene homopolymer has a melt index of about 10 to about 25 g/10 min at 230° C.; (a-2) about 2 to about 8 wt % modified polypropylene resin; and (a-3) about 40 to about 70 wt % long fibers having a length of about 5 to about 20 mm; and a second pellet (B) prepared using a resin composition (B) comprising (b-1) about 1 to about 5 wt % polypropylene homopolymer; (b-2) about 30 to about 45 wt % polypropylene-ethylene copolymer; (b-3) about 50 to about 65 wt % thermoplastic elastomer; and (b-4) about 0 to about 5 wt % inorganic filler.
