Abstract:
Disclosed herein is a polymeric filtration medium including at least one fibrous mat of randomly oriented fibers of a polymer. The polymer has a molecular weight distribution (Mw/Mn) between about 1.4 and about 6 and a melt flow rate greater than about 1000 g/10 minutes. Also disclosed herein are methods of making and using the polymeric filtration medium. Further disclosed herein is a composite filtration medium incorporating the polymeric filtration medium.
