Ion Power introduces a new membrane called  “TUFFion,” which is made from extruded NAFION™ polymer. 

It has improved mechanical properties while still exhibiting the same excellent electrical and transport properties as film  NAFION(tm) membranes.  It achieves this via unique molecular alignment and strengthening processes used during the manufacturing of the membrane. Since no reinforcement structures are used, the TUFFion membrane has improved conductivity and transport properties as compared to traditional membranes with reinforcing structures. It is currently available in 80 micron thickness range and 0.3 meter wide format.
