Abstract: The present invention relates to a polyethylene composition comprising a polyethylene, preferably ≥95.0 wt % of polyethylene, and further (a) ≥100 and ≤500 ppm of a phenolic antioxidant; (b) ≥500 and ≤2500 ppm of an organic phosphite stabiliser; and (c) ≥500 and ≤2500 ppm of a metal stearate with regard to the total weight of the polyethylene composition. Such polyethylene composition, when used in a moulding process with PCR polyethylene, results in a reduction of the quantity of degradation products formed, which may be observed as a reduction of die deposits.
