General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.
Nafion NR50 is a perfluorosulfonic acid nafion resin that is majorly used as a strong solid acid (H0 -12) with high thermal stability and chemical resistance.


Nafion NR50 can be used for a variety of applications such as:
  • a solid acid-catalyst in the synthesis of α-tocopherol
  • a catalyst for cellulose hydrolysis
  • a reference catalyst in the preparation of carbon-based solid acid catalysts
