Polytetrafluoroethylene (PTFE)

PTFE (fine powder resin) is expanded into a 3-dimensional weblike structure called PTFE which creates billions of microscopic pores. This structure utilizes the inherent hydrophobic (waterresistant) and non-stick nature of PTFE to allow removal of particulate captured on the membrane surface. This allows air to pass easily through the membrane while collecting particulate as small as 0.1 micron on its surface. PTFE membranes and laminates provide device manufacturers with a consistent, temperature and chemical compatible barrier to microbes and particulate matter. The optimal combination of air flow and water entry pressure adds value to most device designs.
