Multimodal high density polyethylene
Abstract:
The invention is directed to a multimodal polyethylene having a flow ratio FRR ranging between ≥25 and ≤35, a density ranging between ≥948.0 kg/m3 and ≤953.0 kg/m3, an MFR190/5 ranging between ≥0.1 and ≤0.4 g/10 min and comprising from 50-54% by weight of an ethylene homopolymer A and from 46-50% by weight of an ethylene-hexene copolymer B, where ah percentages are based on the total weight of the composition and wherein ethylene homopolymer A has a viscosity number ≥110 cm3/g and ≤130 cm3/g and a density between ≥960.0 kg/m3 and ≤969.0 kg/m3. The polyethylene is suitable to be applied in the production of pipes.
