Product Uses

Diaion HP-20 is a versatile non-porous adsorbent resin widely utilized in industrial separation and purification processes. Its high surface area and unique pore structure make it exceptionally effective for the adsorption of non-polar and slightly polar organic compounds from aqueous solutions. In the pharmaceutical industry, it is extensively used for the purification of antibiotics, vitamins, and natural product extracts, such as flavonoids and saponins. The food and beverage sector employs HP-20 for decolorization, deodorization, and the removal of bitter compounds from juices, sweeteners, and protein hydrolysates. Additionally, it serves as a critical tool in environmental applications for wastewater treatment, specifically for removing organic pollutants and recovering valuable chemicals from industrial effluents. Its robust chemical stability and regenerability ensure long-term performance in continuous processing systems.
