Title (EN) POLYETHYLENE BLENDS AND EXTRUDATES AND METHODS OF MAKING THE SAME
(FR) MÉLANGES DE POLYÉTHYLÈNES ET EXTRUDATS ET LEURS PROCÉDÉS DE FABRICATION
Abstract:
(EN) A polymer blend including a first polyethylene and second polyethylene is provided, wherein the polymer blend has a density of 0.910 g/cm3 to 0.965 g/cm3 and a melt index (I2.16) of 0.10 dg/min to 10 dg/min. The first polyethylene can include at least 80 mol% ethylene and have: a density of 0.910 g/cm3 to 0.960 g/cm3 and a melt index (I2.16) of 0.10 dg/min to 10 dg/min, and the second polyethylene can include at least 80 mol% ethylene and have: a density of 0.915 g/cm3 to 0.970 g/cm3 and a melt index (I2.16) of 0.01 dg/min to 10 dg/min. Polymer extrudates of the polymer blend, particularly wire- and cable-coatings, as well as methods of making the polymer extrudates are also provided.
(FR) La présente invention concerne un mélange de polymères comprenant un premier polyéthylène et un second polyéthylène, le mélange de polymères ayant une densité de 0,910 g/cm3 à 0,965 g/cm3 et un indice de fusion (I2.16) de 0,10 dg/min à 10 dg/min. Le premier polyéthylène peut comprendre au moins 80 % en mole d'éthylène et présenter : une densité de 0,910 g/cm3 à 0,960 g/cm3 et un indice de fusion (I2.16) de 0,10 dg/min à 10 dg/min, et le second polyéthylène peut comprendre au moins 80 % en mole d'éthylène et avoir : une densité de 0,915 g/cm3 à 0,970 g/cm3 et un indice de fusion (I2.16) de 0,01 dg/min à 10 dg/min. La présente invention concerne également des extrudats polymères du mélange de polymères, particulièrement des gainages de fil et de câble, ainsi que des procédés de fabrication des extrudats polymères.
