    摘要: Disclosed is a polypropylene resin composition for an uncoated crash pad. The composition may include an amount of about 50 to 80 wt % of a polypropylene resin having a Polydispersity Index (PI) of about 4.5 to 6.5, a weight average molecular weight of about 200,000 to 350,000 g/mol, and an isotactic peptide fraction of about 96% or greater as measured by a C13-NMR method, an amount of about 1 to 30 wt % of rubber having a melt index of about 1 to 6 g/10 min (230° C., 2.16 Kg), an amount of about 11 to 30 wt % of an inorganic filler composed of a mixture of an amount of about 10 to 20 wt % of talc and an amount of about 1 to 10 wt % of whisker, and an amount of about 1 to 5 wt % of an anti-scratch agent, all the wt % are based on the total weight of the polypropylene resin composition.

    摘要: Disclosed are a resin composition and a molded article using the same. The resin composition may be obtained by mixing a thermoplastic vulcanizate and a polyethylene resin with a thermoplastic olefin resin, a polypropylene resin, an inorganic filler and a thermoplastic rubber, and in particular, the thermoplastic vulcanizate and the polyethylene resin may be obtained from biologically obtainable materials (biomass). Thus, the resin composition may be environmentally-friendly because it does not emit offensive odor of harmful compounds due to decreased generation of carbon dioxide and volatile organic compounds unlike petroleum-based materials. Further, superior mechanical properties such as elongation, hardness, strength, etc. that cannot be achieved only with conventional biodegradable resin may be ensured, and, at the same time, processability and moldability may be improved.
