Expanded Polytetrafluoroethylene Membranes and Their Applications

The unique properties of expanded polytetrafluoroethylene (ePTFE) membrane make it a good choice for a number of pharmaceutical applications. Currently, ePTFE constructions are used for sterile filtration of fermentation feed air, process gases, and tank venting. They are also used in powder collectors and ultralow penetration air (ULPA) filters. The
