MULTIMODAL POLYETHYLENE COMPOSITION WITH HIGH PRESSURE RESISTANCE |
摘要 |
<p>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 Formula (I) where G'1 - first order Fourier Coefficient G'3 - 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.</p> |
