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： A metallic polypropylene resin composition is provided herein. The metallic polypropylene resin composition provides appearance characteristics that are similar to those provided by painting, but without painting. The metallic polypropylene resin composition of the present invention has excellent physical properties such as scratch resistance, and thus may be applied to molding methods, such as a molded in color (MIC) method. The resin composition is useful as a material for automobile interior and exterior parts, as wells as electric and electronic products, which can be molded by the MIC method.
