There are many different ion exchange resin manufacturers including Purolite, Dow, Sybron/Bayer, Thermax, Rohm and Haas and ResinTech. We are often asked to provide a resin that is the closest equivalent to the ion exchange resin they have or need to purchase. This is a Resin Equivalency list we use internally of the most common ion exchange resins and not an exhaustive list of all ion exchange resin equivalencies. Res-Kem does not guarantee the accuracy of this listing. It is, to the best of our knowledge, correct. Contact us to confirm a selection.
