<p>Polypropylene composition comprising: (i) 30-95 wt.% of a polypropylene (PP); (ii) 2-25 wt.% of a linear low density polyethylene (LLDPE) copolymer of ethylene and 1-butylene with a density between 0.890 and 0.930 g/cm 3 , and a Melt Flow Index (MFI) between 0.1 and 100 g/10min (iii) 3-40 wt.% of a copolymer of ethylene and a C 3 -C 20 ±-olefin with a density between 0.840 and 0.890g/cm 3 and a MFI between 0.1 and 100 g/10min, and (iv) 0-60 wt.% of a filler,
wherein all wt.% are calculated with respect to the total amount (i), (ii), (iii) and (iv) and the ratio of the amount of LLDPE to the amount of the copolymer of ethylene and a C 3- C 20 ±-olefin is less than 1.2.</p> |
