Food Grade Macroporous Weakly Acidic
Acrylic-based Cation Exchange Resin

PRODUCT DATA SHEET:

D113FG is a food-grade 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, this resin is primarily applied in softening alkaline water within various industries as food &beverage, pharmaceuticals, biology industries, etc.

Joint-use with 732 model can reduce the acid consumption of the demineralization system. Another application is widely used in wastewater treatment.
