Main Highlights

Higher Grade 10% Cross Link Cation Resin. Water Softening - Strong Acid Cation Exchange Resin
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 (0.51 mm diameter) microbeads, usually white or yellowish, fabricated from an organic polymer substrate. The beads are typically porous, providing a large surface area on and inside them. The trapping of ions occurs along with the accompanying release of other ions, and thus the process is called ion exchange.
The cation resin is a high purity, premium cation resin designed for the treatment of foods, beverages, water for food processing and most any potable water.
