The invention is directed to polyethylene having a multimodal molar mass distribution, having a density in the range from 940 to 948 kg/m3, having an MFI 190/5 in the range from 1.0 to 3.5 g/10min and comprising from 45 to 47 % by weight of an ethylene copolymer A and from 53 to 55 % by weight of an ethylene copolymer B, where all percentages are based on the total weight of the composition wherein ethylene-1-butene copolymer A has a viscosity number in the range between 70 and 110 cm3/g and a density between 960 and 973 kg/m3. The polyethylene is suitable to be applied in pipe coating applications.
