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.
