Abstract

Una composición de polietileno con una distribución de masa molecular multimodal, que es particularmente adecuada para moldear por soplado pequenos contenedores con un volumen en el rango de 200 a 5000 cm3. (=ml). La composición tiene una densidad en el rango de 0,955 a 0,960 g/cm3 a 23° C, y un índice de flujo fundido IFF190/5 en el rango de 0,8 a 1,6 dg/min.. Ella comprende de 45 a 55% en peso de un homopolímero A de etileno de baja masa molecular, de 20 a 35% en peso de un copolímero B de alta masa molecular preparado a partir de etileno y otra 1-olefina C4-8, y de 20 a 30% en peso de un copolímero C de etileno de ultra alta masa molecular. Un proceso para producir la composición de polietileno y el uso de la composición para producir moldes por soplado pequenos.A polyethylene composition with a multimodal molecular mass distribution, which is particularly suitable for blow molding small containers with a volume in the range of 200 to 5000 cm3. (= ml). The composition has a density in the range of 0.955 to 0.960 g / cm3 at 23 ° C, and a melt flow index IFF190 / 5 in the range of 0.8 to 1.6 dg / min. It comprises 45 to 55% by weight of a low molecular mass ethylene homopolymer A, 20 to 35% by weight of a high molecular mass copolymer B prepared from ethylene and another C4-8 1-olefin, and from 20 to 30% by weight of an ultra high molecular mass ethylene C copolymer. A process to produce the polyethylene composition and the use of the composition to produce small blow molds.
