IPC: C08L23/16

Abstract: The present invention relates to a polyolefin composition comprising a) 20-30 wt% (based on the overall weight of the polymer composition) of at least one polypropylene homopolymer, b) 10-45 wt% (based on the overall weight of the polymer composition) of a blend of recycled plastic material comprising polypropylene and polyethylene in a ratio between 3 : 7 and 49.5:1, which is recovered from a waste plastic material derived from post-consumer and/or post- industrial waste; c) 7-15 wt% (based on the overall weight of the polymer composition) of at least one heterophasic propylene copolymer; d) 1-4 wt% (based on the overall weight of the polymer composition) of at least one elastomer; e) 15-25 wt% (based on the overall weight of the polymer composition) of glass fibers; and f) 0.5-2.5 wt% (based on the overall weight of the polymer composition) of 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 fogging value of 0.5 – 2.00 (measured gravimetrically according to ISO 75201, method B).
