Title (EN) POLYETHYLENE COMPOSITION OF IMPROVED PROCESSABILITY
(FR) COMPOSITION A BASE DE POLYETHYLENE PRESENTANT UNE APTITUDE AU TRAITEMENT AMELIOREE
Abstract:
(EN) The present invention relates to a polyethylene composition, comprising a base resin which comprises (i) a first fraction which is an ethylene homo- or copolymer, and (ii) a second fraction which is an ethylene copolymer, wherein the first fraction (i) has a lower weight average molecular weight than the second fraction (ii), and the base resin has a density of less than 0.940 g/cm3 and a shear thinning index SHI2.7/210 of at least 25.
(FR) La présente invention concerne une composition à base de polyéthylène, comprenant une résine de base comprenant (i) une première fraction constituée d'un homo- ou d'un copolymère d'éthylène, et (ii) une seconde fraction constituée d'un copolymère d'éthylène, la première fraction (i) ayant un poids moléculaire moyen pondéré plus faible que la seconde fraction (ii), et la résine de base ayant une densité inférieure à 0,940 g/cm3 et un indice de fluidification par cisaillement SHI2,7/210 d'au moins 25.
