<p>Composition having a melt flow rate MFR 2 (230 °C) measured according to ISO 1133 in the range of 15 to 30 g/10min,
said composition comprises a heterophasic propylene copolymer (H-PP1), a high melt flow polypropylene (HMF-PP), a styrenic block copolymer (SBC) and a mineral filler (F), wherein
(a) the heterophasic propylene copolymer (H-PP1) has a xylene cold soluble (XCS) content measured according to ISO 6427 in the range of 22.0 to 50.0 wt.-% and comprises
(a1) a polypropylene matrix (M1) and
(a2) an elastomeric copolymer (E1) comprising units derived from
- propylene and
- ethylene and/or C 4 to C 12 ±-olefin,
(b) the melt flow rate MFR 2 (230 °C) measured according to ISO 1133 of the high melt flow polypropylene (HMF-PP) is higher than the melt flow rate MFR 2 (230 °C) measured according to ISO 1133 of the heterophasic propylene copolymer (H-PP1),
and
(c) the high melt flow polypropylene (HMF-PP) has melt flow rate MFR 2 (230 °C) measured according to ISO 1133 of at least 40.0 g/10min.</p> |
