Abstract:
The present invention relates to a polyethylene composition comprising, preferably consisting of, a base resin comprising a copolymer of ethylene and at least two comonomers selected from alpha-olefins having from three to twelve carbon atoms, wherein the ethylene copolymer comprises a low molecular weight component (A) and a high molecular weight component (B) with the low molecular weight component (A) having a lower weight average molecular weight than the high molecular weight component (B), and optional additives, suitable for the production of an article, preferably pipe.
