Product Highlights

  • For use with the Vaisala GM70 CARBOCAP┬« hand-held carbon dioxide (CO2) meter
  • Removes excess humidity in short-term sample draws
  • Extremely resistant to chemical attacks According to DuPont, only metallic alkali metals (sodium in particular) can attack Nafion directly under normal conditions of temperature and pressure
  • Does not release fragments or degradation products into the surrounding medium
  • Relatively high working temperatures compared to many polymers
  • Useful in some applications at temperatures up to 190┬░ C
  • Highly ion-conductive
  • Functions as a cation exchange polymer
  • Super-acid catalyst
  • Sulfonic acid groups attached to the Teflon backbone within Nafion function as an extremely strong proton donor due to the stabilizing effect of the large polymer matrix attached to the sulfonic acid
  • Very selectively and highly permeable to water
  • The sulfonic acid groups in Nafion have a very high water-of-hydration, so they very efficiently absorb water Interconnections between the sulfonic acid groups lead to very rapid transfer of water through the Nafion
