Strongly Acidic Styrene-Based

Cation Exchange Resin


001×7 is a gel-type strongly acidic cation exchange resin of polystyrene series, containing a sulphonic acid functional group. It has excellent physical and chemical stability and thermostable performance. With its additional fine selectivity and high exchange capacity, it is mainly applied in water demineralization system of various industries such as metallurgy, chemical engineering, electric power, electronics, semiconductor, food& beverage, cosmetics and pharmaceuticals.
