Abstract
A polymer composition comprising a base resin is disclosed herein. The base resin includes a very high molecular weight polyethylene component, a low molecular weight polyethylene component having a weight average molecular weight lower than a weight average molecular weight of the very high molecular weight component and a high molecular weight component having a weight average molecular weight higher than the weight average molecular weight of the low molecular weight component, but lower than the weight average molecular weight of the very high molecular weight component. The composition has a complex viscosity at 0.05 rad/s Etaof equal to or more than 800 kPa·s, a viscosity at a shear stress of 747 Pa (eta747) of equal to or less than 34000 kPas and a melt flow rate MFR5 of equal to or less than 0.17 g/10 min.
