Abstract: Bi-modal polyethylene blends made from a high-molecular ethylene copolymer and a low-molecular ethylene homopolymer or copolymer with an MFR 190/21.6 of4 g/10 min, a density of 0.94.97 g/cm , an ESCR > 150h and a blend mixture quality of less than 3 measured according to ISO 13949. The invention also relates to methods for the production of polyethylene blends by means of fusion and homogenization in a mixing unit and discharge via a gear pump. The invention further relates to the use of said blends in the production of shaped bodies, especially hollow bodies and pressure pipes.
