The porous type has a porous matrix structure, and with the same degree of cross-linking, it is highly durable against swelling shrinkage. It is also effective for treatments that require high water quality, such as when silica removal to low concentrations is required. In pharmaceutical treatment, it is also effective when raw process stream contains a lot of organic matter and there is concern about organic pollution. DIAION PA316 is usually used for water treatment. DIAION PA308 is used for desalting and decolorizing sugar solutions. High porous type-I DIAION HPA25 is a highly porous resin with a higher degree of cross-linking than porous type, and is used for better mass transfers.
