Title
(EN) POLYETHYLENE COMPOSITION WITH BROAD MOLECULAR WEIGHT DISTRIBUTION AND IMPROVED HOMOGENEITY
(FR) COMPOSITION DE POLYÉTHYLÈNE À DISTRIBUTION LARGE DU POIDS MOLÉCULAIRE ET HOMOGÉNÉITÉ AMÉLIORÉE
Abstract
(EN)
The present application relates to a polyethylene composition comprising a base resin having a density of at least 948 kg/m3, wherein the composition has a shear thinning index SHI(2.7/210), being the ratio of the viscosity at a complex modulus of 2.7 kPa and of 210 kPa, of 55 or more and 105 or less and a viscosity at a shear stress of 747 Pa, eta747 Pa, of 450 kPas or more, a process for the production of said polyethylene composition, an article comprising said polyethylene composition and the use of said polyethylene composition for the production of an article.
(FR)
La présente invention concerne une composition de polyéthylène comprenant une résine de base ayant une densité d'au moins 948 kg/m3, la composition ayant un indice de fluidification par cisaillement SHI(2,7/210), qui correspond au rapport entre la viscosité à un module complexe de 2,7 kPa et de 210 kPa, supérieur ou égal à 55 et inférieur ou égal à 105, et une viscosité à une contrainte de cisaillement de 747 kPa, eta747 Pa, supérieure ou égale à 450 kPas, un procédé de fabrication de ladite composition de polyéthylène, un article comprenant ladite composition de polyéthylène et l'utilisation de ladite composition de polyéthylène pour la fabrication d'un article.
