Title (EN) POLYETHYLENE FORMULATIONS WITH IMPROVED BARRIER AND ENVIRONMENTAL STRESS CRACK RESISTANCE
(FR) FORMULATIONS DE POLYÉTHYLÈNE À BARRIÈRE ET RÉSISTANCE À LA FISSURATION SOUS CONTRAINTE ENVIRONNEMENTALE AMÉLIORÉES
Abstract:
(EN) Polyethylene formulations and articles produced therefrom, comprise a multimodal high density polyethylene (HDPE) composition, and 0.1 ppm to 300 ppm of a nucleating agent, wherein the multimodal HDPE composition comprises a density of 0.940 g/cm3 to 0.970 g/cm3 when measured according to ASTM D792, and a melt index (I2) of 0.1 g/10 min. to 10.0 g/10 min. when measured according to ASTM D1238 at 190°C and a 2.16 kg load, and wherein the multimodal HDPE composition comprises an infrared cumulative detector fraction (CDFIR) of greater than 0.27 and an infrared cumulative detector fraction to light scattering cumulative detector fraction ratio (CDFIR / CDFLS) from 0.7 to 2.0.
(FR) La présente invention concerne des formulations de polyéthylène et des articles produits à partir de celles-ci, qui comprennent une composition de polyéthylène haute densité (PEHD) multimodale et de 0,1 ppm à 300 ppm d'un agent de nucléation, ladite composition de PEHD multimodale comprend une masse volumique allant de 0,940 g/cm3 à 0,970 g/cm3 lorsque mesurée conformément à la norme ASTM D792, et un indice de fusion (I2) allant de 0,1 g/10 min à 10,0 g/10 min lorsque mesuré conformément à la norme ASTM D1238 à 190 °C et sous une charge de 2,16 kg, et la composition de PEHD multimodale comprenant une fraction de détecteur à infrarouge cumulée (CDFIR) supérieure à 0,27 et un rapport de la fraction de détecteur à infrarouge cumulée à la fraction de détection de la diffusion de la lumière cumulée (CDFIR / CDFLS) allant de 0,7 à 2,0.
