LIGHTWEIGHT EXPANDED POLYTETRAFLUOROETHYLENE MEMBRANES HAVING HIGH INTRINSIC STRENGTH AND OPTICAL TRANSPARENCY

Thin, self-supporting biaxially expanded polytetrafluoroethylene (ePTFE) membranes that have a high crystallinity index, high intrinsic strength, low areal density (i.e., lightweight), and high optical transparency are provided. In particular, the ePTFE membrane may have a crystallinity index of at...
