CSA 9 L

Strong Acid Cation Exchange Resin

DOSHION CSA 9L has a GEL Type Strongly Acidic unifunctional cross linked polystyrene structure containing Sulphonic Acid + Na groups. It is a high capacity gel type resin with excellent physical and chemical properties. Due to its high exchange capacity, it is recommended where hardness of Calcium and Magnesium salts are high. The resin is + primarily used in industrial water softening application in Na form.
