摘要: A polyethylene powder has a molecular weight in the range of about 300,000 g/mol to 2,000,000 as determined by ASTM-D 4020, an average particle size, D 50 , between 300 and 1500 μm, bulk density 0.25 0.5 g/ml. On sintering, produces porous article having porosity at least 45% pressure drop less than 5 mbar. The is useful in, for example, wastewater aeration capillary filtration applications.
