Macroporous Weakly Acidic Acrylic-based

Cation Exchange Resin


D113 is a macro-porous weakly acidic acrylic-based cation exchange resin with a large capacity of carboxylic acid group. Characterized by its excellent physical and chemical stability, it is primarily applied in softening alkaline water. Joint- use with product model #732 can reduce the acid consumption of the demineralization system. Additional applications can be within wastewater treatment.
