"Used as macroporous adsorbent." [ChemIDplus] "Widely used in refining of pharmaceuticals and natural extracts, since these are suitable for adsorbing large molecules because of their relatively large pore sizes and have superior adsorption/ desorption. HP20 and HP21 are widely used in a variety of industrial applications, especially adsorption, desalting and decolorization of natural products and small proteins." [www.diaion.com]
