Abstract

Se divulgan modalidades de formulaciones de polietileno y artículos que comprenden formulaciones de polietileno. La formulación de polietileno puede incluir de 45% en peso a 90% en peso de un MDPE que tiene una densidad de 0,930 g/cc a 0,950 g/cc y un índice de fusión (I₂) de 0,05 g/10 min. a 0,5 g/10 min.; de 10% en peso a 50% en peso de una composición de polietileno que tiene una densidad de 0,910 g/cc a 0,936 g/cc y un índice de fusión (I₂) de 0,7 g/10 min. a 1,0 g/10 min.; y de 0,5% en peso a 5% de una composición de mezcla maestra. La composición de polietileno puede comprender una área de la primera fracción de polietileno en un intervalo de temperatura de 45ºC a 87ºC de un perfil de elución a través del método de análisis de distribución de composición de comonómeros mejorada (iCCD) y un área de la segunda fracción de polietileno en un intervalo de temperatura de 95ºC a 120ºC de un perfil de elución a través de iCCD.
