TuffBrane™
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.

technology
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.
