Strong Base Anion Exchange Resin

Alfa Chemistry is a new industry and new material technology company integrating R&D, resin production, sales, service. We supply various types of ion exchange resins.

Strong base anion ion exchange resins are based on a polystyrene or polyacrylic matrix with either gel and macroporous structures with a quaternary ammonium group and can dissociate just like NaOH and KOH. They can be used for dealkalization, deionization, demineralization and organic removal.

Here lists our strong base anion exchange resins and their technical data. Please feel free to contact us for more details.
