Automotive material with excellent flow, high stiffness, excellent ductility and low CLTE

摘要

Composition having a melt flow rate MFR 2 (230 °C) in the range of 10 to 50 g/10min. said composition comprises two heterophasic polypropylenes comprising a propylene homopolymer matrix and an elastomeric copolymer. a plastomer and a mineral filler. wherein
- said two heterophasic polypropylenes have different melt flow rates.
- the first heterophasic polypropylene has a melt flow rate MFR 2 (230 °C) in the range of 3.0 to 30.0 g/10min and
- the second heterophasic polypropylene has a xylene cold soluble (XCS) content in the range of 7.0 to 20.0 wt.-%.
