Met blown polymeric filtration medium for high efficiency fluid filtration

摘要

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 (M w /M n ) 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 the polymeric filtration medium. Further disclosed herein is a composite filtration medium incorporating the polymeric filtration medium.
