An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange. It is an insoluble matrix (or support structure) normally in the form of small (0.25–1.43 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate.
Ion exchange is a reversible chemical reaction where dissolved ions are removed from solution and replaced with other ions of the same or similar electrical charge. Not a chemical reactant in and of itself, IX resin is instead a physical medium that facilitates ion exchange reactions.

Ion exchange resins are highly ionic, covalently cross-linked, insoluble polyelectrolytes supplied as beads. The beads have either a dense internal structure with no discrete pores (gel resins, also called microporous resins) or a porous, multichannelled structure (macroporous or macroreticular resins).
Ion exchange resins consists of two main types, i.e., cation exchange resins, that exchange positively charged ions, such as sodium, for calcium, and anion exchange resins, that exchange negatively charged ions, such as chloride, for arsenic.
Ion exchange resins are the physical medium that facilitates ion exchange reactions. The resin is composed of cross-linked organic polymers, typically polystyrene matrix and functional groups where the ion exchange process takes place.
We manufacture world class ion exchange resins of all types - gel, macroporous and isoporous, for water, non-water and speciality applications in industries such as pharma, food & beverage, nuclear, chemical, bio-diesel, hydrometallurgy, sugar and many more.
Jul 26, 2022 · Definition: Ion Exchange Resins. Ion exchange resins are insoluble polymers formed by crosslinking of polystyrenes with different functional groups, which act as a medium for ion exchange reactions.
Ion-exchange resin, any of a wide variety of organic compounds synthetically polymerized and containing positively or negatively charged sites that can attract an ion of opposite charge from a surrounding solution. The resins commonly consist of a styrene-divinylbenzene copolymer (high molecular.
Jan 1, 2012 · Considering the separation mechanism, ion exchangers can be further classified into various categories including ion exchange resins, chelating adsorbents, hydrogels, affinity polymers, and ion exchange membranes.
