Abstract
The invention relates to a polypropylene composition comprising: (i) 30-97 wt. % of a polypropylene; (ii) 2-20 wt. % of a branched low density polyethylene with a density between 910 and 935 kg/m3 and a Melt Flow Index (MFI) between 0.1 and 100 g/10 min; (iii) 1-20 wt. % of a copolymer of ethylene and a C3-C20 α-olefin with a density between 840 and 890 kg/m3 and a Melt Flow Index (MFI) between 0.1 and 100 g/10 min; and (iv) 0.5-60 wt. % of a filler, wherein wt. % are calculated on the total amount of the polypropylene composition.
