Porous type DIAION™ PK Series
The PK resin grades are based on a porous styrene DVB polymer matrix. Their porous structure provides excellent durability against osmotic shock by swelling and shrinkage. PK216 is recommended for general water treatment. PK228 is recommended for condensate demineralization (L grade is recommended for best pressure-flow performance). PK grades are also recommended for special applications such as de-ashing, decolorization, and as a catalyst (as they have a higher reaction rate in organic solvents than gel-type resins).
