Advance the energy landscape
The toughest Anion Exchange Membrane on the planet with out of this world performance.
TuffBrane™ delivers the benefits of an AEM with performance and durability rivaling a PEM.
TuffBrane™ is a patented Anion Exchange Membrane with excellent performance and durability.
100% hydrocarbon polymer chemistry
High ionic conductivity - 180 mS/cm (σOH-)
Long durability in harsh alkaline environments
Low swelling ratio - <10%
High mechanical strength
High chemical stability - 0-14 pH
These impressive qualities are achieved through a polyethylene backbone chemistry, and when hydrated, the membrane gets even stronger.
The result is a low-cost, high performance membrane that will reduce capital and operational expenses for many applications.
