    摘要: The present invention relates to a polyolefin composition comprising a) 5-30 wt% (based on the overall weight of the polyolefin composition) of at least one polypropylene homopolymer, b) 1-15 wt% (based on the overall weight of the polyolefin composition) of at least one polypropylene block copolymer, c) 20-50 wt% (based on the overall weight of the polyolefin composition) of a mixed-plastics polypropylene blend of recycled material, d) 35-55 wt% (based on the overall weight of the polyolefin composition) of glass fibers; and optionally further additives, wherein the sum of all ingredients adds always up to 100 wt%, wherein the polyolefin composition has a tensile modulus at 23°C of at least 7000 MPa (ISO 527-2), a tensile stress at yield at 23°C of at least 90 MPa (ISO 527-2), and an impact strength (ISO179-1, Charpy 1eA +23°C) of at least 8.5 kJ/m 2 .
