Title (EN) POLYETHYLENE FORMULATIONS WITH IMPROVED BARRIER AND TOUGHNESS FOR MOLDING APPLICATIONS
(FR) FORMULATIONS DE POLYÉTHYLÈNE À BARRIÈRE ET TÉNACITÉ AMÉLIORÉES DESTINÉES À DES APPLICATIONS DE MOULAGE
Abstract:
(EN) Polyethylene formulations, articles produced therefrom, and methods of making articles are provided. The polyethylene formulation includes a multimodal high density polyethylene (HDPE) composition, and 1 ppm to 10,000 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 0.01 g/10 min. to 1.0 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) L'invention concerne des formulations de polyéthylène, des articles produits à partir de celles-ci, et des procédés de fabrication d'articles. La formulation de polyéthylène comprend une composition de polyéthylène haute densité (PEHD) multimodal, et 1 ppm à 10 000 ppm d'un agent de nucléation, la composition de PEHD multimodal comprenant une masse volumique de 0,940 g/cm3 à 0,970 g/cm3 lorsqu'elle est mesurée selon la norme ASTM D792, et un indice de fusion (I2) de 0,01 g/10 min. à 1,0 g/10 min. lorsqu'il est mesuré selon la norme ASTM D1238 à 190 °C et sous une charge de 2,16 kg, et la composition de PEHD multimodal comprenant une fraction cumulée de détecteur infrarouge (CDFIR) supérieure à 0,27 et un rapport entre la fraction cumulée de détecteur infrarouge et la fraction cumulée de détecteur à diffusion de lumière (CDFIR / CDFLS) de 0,7 à 2,0.
