摘要

Heterophasic polypropylene composition comprising a polypropylene (PP), an elastomeric propylene copolymer , and a mineral filler (F), wherein
(i) said heterophasic polypropylene composition has a melt flow rate MFR 2 of equal or below 2.0 g/10min,
(ii) said heterophasic polypropylene composition has a polydispersity index (PI) of at least 5.0,
(iii) the amount of the amorphous fraction of the xylene cold soluble fraction of the heterophasic polypropylene composition is at least 5.0 wt.-%, and
(iv) the amount of mineral filler within said heterophasic polypropylene composition is in the range of 5.0 to equal or below 30.0 wt.-%.
