Tulsion®-A-27

Tulsion® A-27 is a strong base anion exchange resin with an isoporous type structure based on polystyrene matrix, containing quaternary ammonium Type I group. The strong base groups, derived from quaternary ammonium groups, are capable of removing weak acids such as silicic and carbonic acids to very low levels. Tulsion® A-27 is supplied as moist spherical beads in the chloride form with a controlled particle size distribution to provide excellent kinetics and minimal pressure loss. Tulsion® A-27 is highly basic. In water treatment, it is employed in a hydroxide form along with the strong acid cation exchanger, Tulsion® T-42 in H+, both in two bed and mixed bed systems to produce high quality de- ionized water, giving effluent with low silica residuals and low conductivity. Besides its primary application in water treatment, Tulsion® A-27 is also commonly used for de-alkalization and other chemical processes. This resin has also better resistance to organic matter.
