Composition

Abstract

The invention provides a polymer composition comprising: (i) 95.0 to 99.95 wt %, relative to the total weight of the polymer composition, of a multimodal high density polyethylene (HDPE) with a density of 945 to 980 kg/m3 measured according to ISO 1183, and an MFR2 of 0.1 to 1.3 g/10 min measured according to ISO 1133 at 190° C. and a load of 2.16 kg; and wherein the multimodal HDPE comprises at least two fractions: (A) 30 to 70 wt %, relative to the total weight of the multimodal HDPE, of a lower molecular weight fraction being a polyethylene with a density in the range of 955 to 980 kg/m3 measured according to ISO 1183 and an MFR2 of 100 to 600 g/10 min measured according to ISO 1133 at 190° C. and a load of 2.16 kg; and (B) 30 to 70 wt %, relative to the total weight of the multimodal HDPE, of a higher molecular weight fraction being a polyethylene with a density in the range of 930 to 960 kg/m3 measured according to ISO 1183 and an MFR2 of 0.0001 to 1.0 g/10 min measured according to ISO 1133 at 190° C. and a load of 2.16 kg; and (ii) 0.05 to 0.5 wt %, relative to the total weight of the polymer composition, of at least one saturated amide slip agent.
