Highly Porous-Type DIAION™ HPA25L (Type I)

Highly porous type resin, HPA25L, has higher cross-linkage and higher porous properties than standard PA grade resins. This is typically used for the treatment of large molecules in special process applications. They are mainly applied in enzyme purification as enzyme carriers for the treatment of bio-pharmaceutical substances, and treatment of feed solutions of high color value.
