Title (EN) POLYETHYLENE COMPOSITIONS
(FR) COMPOSITIONS DE POLYÉTHYLÈNE
Abstract:
(EN) Provided are various compositions, including but not limited to a bimodal polyethylene composition having a density of 0.940 g/cc or more, the composition comprising a high molecular weight polyethylene component and a low molecular weight polyethylene component, wherein the composition qualifies as a PE 100 material such that in accordance with ISO 1167 a pipe formed from the composition that is subjected to internal pipe resistance has an extrapolated stress of 10 MPa or more when the internal pipe resistance curve is extrapolated to 50 or 100 years in accordance with ISO 9080:2003(E), and wherein the melt strength is greater than 18 cN.
(FR) L'invention porte sur diverses compositions, comprenant mais sans y être limitées, une composition de polyéthylène bimodal dont la masse volumique est de 0,940 g/cm3 ou plus, la composition comprenant un composant polyéthylène de masse moléculaire élevée et un composant de polyéthylène de faible masse moléculaire, la composition remplissant les conditions d'un matériau de PE 100 de telle sorte que, selon la norme ISO 1167 un conduit formé à partir de la composition qui est soumis à une résistance de conduit interne présente une contrainte extrapolée de 10 MPa ou plus lorsque la courbe de résistance de conduit interne est extrapolée de 50 à 100 ans selon la norme ISO 9080:2003(E), et la résistance à l'état fondu étant supérieure à 18 cN.
