CSA 9

Strong Acid Cation Exchange Resin

DOSHION CSA 9 is a GEL Type Strong Acid Cation Exchange Resin product by the sulfonation of styrene-divinylbenzene copolymers. The resin is designed to combine high operational capacity and superior physical stability. This quality is assured by specifications that call for a whole un-cracked bead content of at least 95% and an unmatched bead strength. DOSHION CSA-9 is the resin of choice whenever high performance is required. The resin is available in both Na+ and H+ form.
DOSHION CSA 9 can also be supplied with such particle size and density characteristics that will assure fast and sharp separations when used in combination with DOSHION ASB-1 08 or DOSHION GA-11 anion resin in mixed bed applications.
