Nuclear Grade Strongly Acidic Styrene-based Cation Exchange Resin


001×7FB 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 floating bed system to process pure water and ultra-pure water preparation.
