Abstract
The invention relates to an ethylene polymer comprising a low molecular weight component and a high molecular weight component, wherein—the ethylene polymer has a density of 955 to 977 kg/mand a viscosity value η100 of at most 1500 Pa·s and a strain hardening as determined according to ISO18488 of at least 25 MPa, for example 30 to 40 MPa,—the amount of the low molecular weight component with respect to the total ethylene polymer is at least 60 wt %,—the low molecular weight component has a Mw of 10,000 to 50,000 g/mol, a ratio of Mw/Mn of 2.5 to 4.5 and a density of 965 to 985 kg/mand—the high molecular weight component has a Mw of 100,000 to 1,000,000, a ratio of Mw/Mn of 2.5 to 4.0 and a density of 920 to 950 kg/m.
