Aquivion PFSA (perfluoro sulfonic acid polymer) is a functionalized perfluoro-ionomer produced from vinyl fluoride monomer and sulfonyl fluoride vinyl ether. The polymer’s short, low molecular weight side chains make it unique among ionically conductive perfluoropolymers and impart unique performance advantages.

• Higher crystallinity for improved mechanical properties
• Enhanced proton (and also Li+, Na+, K+) conductivity
• Best-in-class ion conductivity, especially at high temperatures
  and low humidity
• Very high functionality combined with excellent thermo-chemical resistance
• Lower equivalent weight than competitive polymers
• Shorter side chains than other ionically conductive perfluoropolymers
• Unique combination of powerful functionality and excellent
  thermo-chemical resistance    

Typical Membrane Applications

• Polymer electrolyte fuel cells (PEFC)
• Electrolyzers
• Gas humidification and pervaporation systems
• Metal-ion recovery cells (Donnan dialysis)

Typical Dispersion Applications 

• Surface modifier for membrane filtration devices
• Super acid catalyst systems
• Electrochemical sensors
• Cationic exchange resins
• Electro-active polymers
• Drug release devices
