    摘要： Polypropylene composition comprising
    (A) 60 to 95 wt% of a heterophasic polypropylene (HECO) comprising 10 to 30 wt% of dispersed phase with the dispersed phase having a comonomer content of 30 to 45 wt% and the HECO having a melt flow rate MFR PP in the range of 12 to 200 g/10 min and being prepared in the presence of a Ziegler Natta catalyst (ZN-C), (B) 0 to 15 wt% of one or more elastomers, (C) 5 to 20 wt% of at least one filler wherein the polypropylene composition fulfils inequation (1) fogging ≤ 0.02 MFR Comp + 0.3.
    The composition allows for a well-balanced combination of a good impact/stiffness balance, a good scratch resistance, low VOC and FOG emissions and remarkable good fogging values.
