  • POLYETHYLENE POWDERS AND POROUS ARTICLES PRODUCED THEREFROM
    Publication number: 20130046040
    Abstract: A polyethylene powder has a molecular weight in the range of about 300,000 g/mol to about 2,000,000 g/mol as determined by ASTM-D 4020, an average particle size, D50, between about 300 and about 1500 ?m, and a bulk density between about 0.25 and about 0.5 g/ml. On sintering, the polyethylene powder produces a porous article having a porosity of at least 45% and a pressure drop less than 5 mbar. The porous article is useful in, for example, wastewater aeration and capillary and filtration applications.
