Abstract:
Polymer composition comprising at least one polypropylene homopolymer and/or random copolymer, up to 15 wt % of at least one polyethylene, optionally at least one elastomer in an amount of 8 to 40 wt % and optionally fillers and/or additives in an amount of up to 45 wt % based on the total weight of the final polymer composition with the at least one polyethylene having a density of higher than 940 kg/m3, a content of hexane hot extractables of below 0.80 wt % preferably below 0.60 wt %, most preferably below 0.40 wt % and a copolymer/homopolymer (COHO) ratio measured by Temperature Rising Elution Fraction (TREF) up to 6%.
