Title
(EN) POLYETHYLENE COMPOSITION FOR HIGH PRESSURE RESISTANT PIPES
(FR) COMPOSITION DE POLYÉTHYLÈNE POUR TUYAUX RÉSISTANTS À HAUTE PRESSION
Abstract
(EN)
The present invention relates to a polyethylene composition comprising a base resin having a density of from 950.0 kg/m³ to 962.0 kg/m³, determined according to ISO 1183, wherein the polyethylene composition has a melt flow rate MFR21 (190°C, 21.16 kg), of from 1.0 to 9.0 g/10 min, determined according to ISO 1133 and a viscosity at a constant shear stress of 747 Pa eta747 of from 3500 kPa‧s to 20000 kPa‧s, a polyethylene composition obtainable by a multi-stage process, a process for producing said polyethylene composition, an article, such as a pipe or pipe fitting, comprising said polyethylene composition and the use of said polyethylene composition for the production of an article, such as a pipe or pipe fitting.
