(a) a high melt strength polypropylene having a melt flow rate MFR 2 (230 °C) of equal or below 15 g/l 0min and a branching index g' of below 1.0,
(b) a first heterophasic propylene copolymer comprising
€¢ a polypropylene having a melt flow rate MFR 2 (230 °C) in the range of 50 to 500 g/10min and an elastomeric propylene copolymer having a propylene content in the range of 50 to 80 wt.-% and
€¢ an intrinsic viscosity (IV) of equal or more than 2.5 dl/g,
(c) a second heterophasic propylene copolymer comprising
€¢ a random propylene copolymer having a melt flow rate MFR 2 (230 °C) in the range of 1 to 40 g/10min, a branching index g' of 1.0, and a comonomer content of more than 0.5 wt.-%,and
€¢ an elastomeric propylene copolymer having a propylene content in the range of 50 to 80 wt.-%, and an intrinsic viscosity (IV) of equal or below 2.4 dl/g,
(d) a polyethylene plastomer having an ethylene content of at least 50 wt.-%, and
(e) a mineral filler (F).</p> |
