Ion Exchange Resins

At UDEC, we understand that different industries have different needs when it comes to Ion Exchange Resins. That’s why we offer the broadest range within the industry:

Weak Acid Cation

Available in polyacrylic, gel or macro ion exchange beads. They have the unique carboxylic acid functions.


These are a special set of resins for ion exchange processes where there is a high presence of competing ions.

Mixed Bed Resin

Mixed bed resins are composed of strong cationic and anionic ion exchangers based on a polystyrene-divinylbenzene matrix that are usually sold in the ready to use (active) ionic forms.

Strong Acid Cation

Strong acidic cation resins are bead sized co-polymers (mainly polystyrene-divinylbenzene) with a sulfuric group which attracts cations. Comes in gel or macroporous types and are available in several bead sizes to adapt to different applications.

Strong Base Anion

Strong base anion resins are bead sized co-polymers (mainly polystyrene-divinylbenzene) with a tertiary or quaternary ammonium group which removes anions in various processes. This product comes in gel or macroporous type and is available in different bead sizes.

Weak Base Anion

Weak base anion resins are bead sized co-polymers (mainly polystyrene-divinylbenzene) with tertiary ammonium groups, which are usually macroporous in structure.

Inert Resins

These are non-functionalised inert media made from Polypropylene or Polyethylene to protect tank nozzles or act as layers in packed beds and mechanical filters.

With over 35 years of experience, UDEC is the innovative industry leader and specialist in process materials, speciality chemicals and adsorbents.
