Our products and technologies are used in two primary segments: energy storage and separations media. 

Energy Storage

In the energy storage segment, our membrane separators are a critical performance component in lithium and lead-acid batteries, performing the core function of regulating ion exchange, allowing the charge and discharge process to occur between a battery's positive and negative electrodes.  Primary applications for our membranes in this segment are lithium batteries and lead-acid batteries.  Lithium batteries are the power source in a wide variety of electronic applications ranging  from laptop computers and mobile phones to power tools, and are emerging in applications such as hybrid electric vehicles (HEVs).  Lead-acid batteries are used in transportation and industrial applications. 

Separations Media

In the separations media segment, our filtration membranes are used in healthcare and high-performance industrial and specialty filtration applications.  These membranes perform the critical function of removing sub-micron particulates from fluid and introducing or removing gases (gasification/degasification) within liquids.  Primary applications for our membranes and membrane modules in this segment are hemodialysis, blood oxygenation, plasmapheresis, and various high performance microfiltration, ultrafiltration and gasification/degasification applications.
