Nuclear Grade Strongly Acidic
Styrene-based Cation Exchange Resin


732H is a nuclear-grade gel-type strongly acidic cation exchange resin of the sulphonated polystyrene type. It has excellent physical and chemical stability and thermostable performance. With its additional fine selectivity and high exchange capacity, it is mainly applied in the water desalting process within various industries such as metallurgy, chemical engineering, electric power engineering, electronics, semiconductor, food& beverage, cosmetics, and pharmaceuticals, etc.
