CSA 609D

DOSHION CSA-609D is a Macroporous Strongly Acidic Cation Exchange Resin. It is based on polystyrene matrix with sulfonic acid functional groups. Due to its highly cross linked matrix and macroporous structure, this resin has exceptional physical strength and chemical stability. The highly cross linked structure provides greater resistance to oxidants and insures longer resin life under aggressive operating conditions. The high degree of cross linking also contributes physical strength and rigidity to the DOSHION CSA-609D resin beads, thus preventing fracture or breakage due to osmotic shock. The sizing of this resin is such that the pressure drop in service will be low and the separation will be good in mixed bed operation.
