Abstract

The present invention relates to a polyolefin composition comprising a) at least one polypropylene homopolymer, b) 10-45 wt% (based on the overall weight of the polyolefin composition) of a mixed-plastics polypropylene blend of recycled plastic material; c) glass fibers; and d) at least one coupling agent, and optionally further additives, wherein the sum of all ingredients add always up to 100 wt%; wherein the polyolefin composition has a melt flow rate MFR<2> (230°C, 2.16 kg, measured according to ISO 1133) of at least 5 g/10 min; a tensile modulus at 23°C of at least 5000 MPa (ISO 527-2), and a tensile stress at yield at 23°C of at least 80 MPa.
