Beschreibung
Zusammenfassung:	A pipe or a supplementary pipe article comprising a polyethylene composition comprising a base resin which comprises (A) a first ethylene homo- or copolymer fraction having an MFR 2 in the range of 300 to 700 g/10 min, and (B) a second ethylene homo- or copolymer fraction, wherein fraction (A) has a lower average molecular weight than fraction (B), wherein the base resin has a density in the range of 0.945 to 0.949 kg/cm 3 and an MFR 5 in the range of 0.2 to 0.4 g/10 min and a comonomer content of higher than 2.0 wt.-% and a SHI(2.7/210) in the range of 55 to 100.
