Abstract:
The invention is directed to bimodal polyethylene having a flow ratio FRR ranging between ≥30 and ≤40, a density ranging between ≥949.0 and ≤952.0 kg/m3, an MFR190/5 ranging between ≥0.1 and ≤0.2 g/10 min and comprising from 50 to 54% by weight of an ethylene homopolymer A and from 46-50% by weight of an ethylene-butene copolymer B, where all percentages are based on the total weight of the composition and wherein ethylene homopolymer A has a viscosity number ≥70 and ≤100 cm3/g and a density between ≥968 and ≤972 kg/m3. The polyethylene is suitable to be applied in the production of pipes.
