Abstract

Membranas de polímero sintético con poros grandes que dan puntos de burbujeo en el intervalo de 0,5 a 25 psid y características de flujo superiores. Las membranas pueden colarse a partir de dispersiones metaestables y de formulaciones para colada homogéneas. La técnica de síntesis implica la exposición de la membrana colada a aire húmedo para crear grandes poros superficiales sobre el lado expuesto.
