Abstract
The present invention relates to a polyolefin blend with a good balance between stiffness and toughness. The polyolefin blend has (i) a melt flow rate MFR<2> (ISO 1133, 230 °C, 2.16 kg) in the range of from 1.0 to 20.0 g/10 min; and (ii) a Charpy Notched Impact Strength (ISO 179-1eA, 23 °C) of more than 4.0 kJ/m<2>; and it comprises (A) 80 to 98 wt.-% of a recycled polyethylene-polypropylene composition (A) with specific characteristics; and (B) 2 to 20 wt.-% of a specifically selected polypropylene (B). The present invention further relates to a method of preparing the polyolefin blend, an article comprising the same and the use of the polyolefin blend in automotive and/or packaging applications. Still further, the present invention is directed to the use of the polypropylene (B) for improving the balance between stiffness and toughness of a recycled polyethylene-polypropylene composition (A) by blending both components.
