201x4 is a Gel Type Strong Base Anion Exchange Resin based on polystyrene matrix with quaternary ammonium functional group. 201x4 gives high throughput and consistent quality. 201x4 resins in combination with 001x7 resins, gives excellent performance in mixed beds. 
 201x4 is high capacity resin which achieves lowest possible silica under varied water conditions. The resin is supplied in transparent moist bead form with high beads strength. The resin is suitable for demineralization system incorporating co-current and counter-current operations.
 APPLICATIONS: 201x4 is recommended in the two bed system of demineralization system. The resin has a lower silica and carbonic acid leakages, hence gives higher silica removal capacity in demineralization units. 201x4 is also used as a mixed bed resin along with 001x7 as a polishing unit to achieve lowest residual silica in treated water and water of high purity is obtained. The resin is also used in absorption process, fractionalization process of weak acid, biochemical’s and pharmaceutical intermediates. 201x4 and 201x7 are quite similar, the difference between them is the degree of porosity. 201x4 has greater porosity that gives it faster kinetics, and greater ability to reversibly sorb slow moving ions such as Naturally occurring Organic Matter (NOM). At lower regeneration levels and where chlorides make up a substantial portion of the anion load, or where the removal and elution of naturally occurring organics is of concern 201x4,202 should be considered. At the higher regeneration levels used in mixed bed polishers 201x7 provides higher capacity, and the lowest possible TOC leach rates.
