摘要：
The present invention relates to a polyethylene composition comprising a base resin which comprises
(a) an ethylene homo- or copolymer fraction (A); and
(b) an ethylene homo- or copolymer fraction (B),
wherein
(i) fraction (A) has a lower average molecular weight than fraction (B);
(ii) the base resin has a density of 940 to 947 kg/m 3 ;
(iii) the polyethylene composition has an MFR 5 of 0.1 to 0.5 g/10 min; and
(iv) the polyethylene composition has an SHI (2.7/210) of 10 to 49.
Furthermore, the present invention relates to an article, preferably a pipe comprising said composition and to the use of said composition for the production of an article, preferably a pipe.
