More Information
Summary:Provided is a polyolefin composition including a) at least one polypropylene homopolymer; b) a blend of recycled plastic material including polypropylene and polyethylene in a ratio between 3:7 and 10:1, which is recovered from a waste plastic material derived from post-consumer and/or post-industrial waste; c) glass fibers; and d) at least one coupling agent. The polyolefin composition has a melt flow rate MFR2 (230° C., 2.16 kg, measured according to ISO 1133) of at least 2 g/10 min; a tensile modulus (ISO 527-2) of at least 4 GPa, and an impact strength (ISO179-1, Charpy 1eA +23° C.) of at least 6 kJ/m2.
