摘要: The present invention relates to a multimodal polyethylene composition which can be manufactured into pipes showing improved pressure resistance comprising a high density multimodal ethylene polymer component (A) having a density of at least 930 kg/m3, and a MFR21 of not more than 15 g/10 min, wherein said composition exhibits a LAOS-NLF defined as L A O S - N L F = G 1 ′ G 3 ′ where G1′—first order Fourier Coefficient G3′—third order Fourier Coefficient of at least 1.7. Such a polyethylene composition is useful for the manufacture of pressure pipes that exhibit improved pressure resistance and creep resistance and do not undergo sagging. Further disclosed is a process for the production of a pipe using such a multimodal polyethylene composition and a pipe comprising such a multimodal polyethylene composition.
