Food Grade Macroporous-type Strongly Acidic Styrene-based Cation Exchange Resin


D001FG is a food grade strongly acidic cation exchange resin of the sulphonated polystyrene series, with a clear macroporous structure. It has excellent physical and chemical stability and thermostable performance. With its additional smart selectivity and large exchange capacity, D001FG model is mainly used for desalting, refining and softening in food &beverage, medicine &pharmaceuticals and sugar manufacturing industries.
