Abstract

Una composicion de polietileno multimodal que comprende una resina base con tres fracciones de homo- o co-polímero de etileno (A), (B) y ( C ) con diferentes promedios ponderados de pesos moleculares Mw, donde: a) la fraccion (A) tiene una MFR21 menor o igual de 20g/10minutos, b) la fraccion (B) tiene u promedio ponderado de pesos moleculares menor que la fraccion ( C ), (c) la fraccion ( C ) tiene un promedio ponderado de pesos moleculares menor que la fraccion (A), d) la composicion tiene una viscosidad de 350kPas o mayor a un esfuerzo de corte de 747Pa (eta 747), y e) la composicion tiene una MFR5 de 0,15g/10minutos o mayor y un área de manchas blancas del 1% o menor. Además, la presente se refiere a un proceso para producir una composicion con dichas características así como al uso de una composicion con dichas características para producir una tubería, para aplicaciones de moldeado, y aplicaciones en alambres y cables.
