Beschreibung
Zusammenfassung:	The present invention relates to a polymer composition, comprising:(a) 60-80 wt% of a recycled polypropylene (rPP);(b) 0-0.03 wt% of a peroxide;(c) 3-7 wt% of a heterophasic propylene ethylene copolymer;(d) 10-30 wt% of a polyolefin elastomer (POE);wherein components (a) to (d) combine to 100%, and wherein the melt flow rate of component (a) has been increased by reaction with a peroxide to be in the range of 60 to 80 g/10 min. determined according to ISO 1133 at 2.16 kg at 230°C. The invention further relates to a process for forming the polymer composition wherein in a first step the MFR of component (a) is increased by reaction with a peroxide, and in a second step components (a)-(d) are added. The invention further relates to articles made from the new polymer composition.
