ABSTRACT
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
unique properties of ePTFE are also being exploited in a number of new innovative
products and technologies. Lyophilization trays, product isolators, and drug delivery
devices are just a few of the new areas of interest to the pharmaceutical industry. This
chapter will:
