Abstract

The present invention relates to a polyethylene composition comprising—a base resin comprising (A) a first ethylene homo- or copolymer component having a melt flow rate MFR2 (2.16 kg, 190° C.) of equal to or more than 150 g/10 min to equal to or less than 300 g/10 min, determined according to ISO 1133, and (B) a second ethylene homo- or copolymer component, —optional carbon black, —optional further polymer component(s) different to the first ethylene homo- or copolymer components (A) and (B), and —optional additive(s); wherein the first ethylene homo- or copolymer component (A) has a lower weight average molecular weight as the second ethylene homo- or copolymer component (B), and the weight ratio of the first ethylene homo- or copolymer component (A) to the second ethylene homo- or copolymer component (B) is from 40:60 to 47:53; the polyethylene composition has a melt flow rate MFR5 (5 kg, 190° C.) of equal to or more than 0.35 g/10 min to equal to or less than 0.60 g/10 min, determined according to ISO 1133. The invention further relates to a process for the production of such a polyethylene composition, an article, such as a pipe or pipe fitting comprising such a polyethylene composition and the use of such a polyethylene composition for the production of such an article.
