摘要: A polyethylene powder is described having a molecular weight in the range of from 3,000,000 g/mol to less than 4,000,000 g/mol as determined by ASTM 4020 and a bulk density of 0.10 to 0.20 g/cm3. On sintering, the polyethylene powder produces a porous article having an elastic modulus of at least 90 MPa.

摘要: 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, D 50 , between about 300 and about 1500 μm, 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.
