St Base 1 Acrylic Anion (EA-S1-AC)
Ecologix Systems US Resin EA-S1AC (Cl or OH form) resin is a high capacity, organicfouling resistant porous gel Type I strong base acrylic anion exchange resin. It is supplied in both chloride and hydroxide forms. Its intended applications include all types of demineralization and chemical processing.
US Resin EA-S1AC is strongly recommended for multiple or mixed bed demineralizers where complete demineralization and organic fouling resistance are required. Its higher porosity and acrylic structure provide increased resistance to organic fouling compared with styrene-based Type I strong base anion resins, such as US Resin EA-S1.
US Resin EA-S1AC (Cl) can also be used with sodium cycle strong acid softening resins such as US Resin C-8(Na), to remove colorcausing organics such as tannins. This is important in some softening applications.
Typical Physical, Chemical & Operating Characteristics
Chemical and Thermal Stability
Ecologix Systems' EA-S1 (OH) resin is insoluble in dilute or moderately concentrated acids, alkalies, and in all common solvents. However, exposure to significant amounts of free chlorine, “hypochlorite” ions, or other strong oxidizing agents over long periods of time will eventually break down the crosslinking. This will tend to increase the moisture retention of the resin, decreasing it s mechanical strength, as well as generating small amounts of extractable breakdown products. Like all conventional el type polystyrene Type I strong base anion resins, it is thermally stable to 60oC (140 oF). The hydroxide form tends to degrade in water temperatures appreciably higher than 52 oC (125 oF), thereby losing capacity, as the functional groups are gradually replaced by hydroxyl groups.
