In this harsh environment, Nafion™ membranes boast lower power consumption, the highest caustic quality, superior pressure excursion reliability, constant production levels, and unmatched technical support to maximize your returns. » More

Catalyst: Nafion™ polymer also acts as a super acid catalyst. When used in solid form, it can be recycled and reused in many acid-catalyzed chemical reactions. Although higher value than typical sulfuric acid catalysts, the solid state nature and ability to be reused and regenerated offers total cost of ownership benefits and can provide desired impurity profiles.

Semiconductor: Chemicals used in semiconductor manufacturing require ultra-high purity. The selectivity of Nafion™ membranes in various electrochemical processes provides ultra-high pure compounds in a cost-effective manner.

Waste Recovery: Membranes can be used to reduce wastes in the maintenance and purification of plating baths, and in the recovery of spent solutions and rinse waters.

Ion Exchange Resins: Nafion™ resins serve as long life, perfluorinated cation exchange resins that can perform in harsh temperatures and chemical environments where other non-fluorinated resins cannot.
