Cation Exchange Resin Resinex ™ K-8

It is a strong acid gel cation exchange resin. The cross-linked polystyrene divinylbenzene matrix provides excellent resistance to physical degradation. The high capacity achieved in softening and demineralization makes it suitable for most standard residential and industrial water treatment applications. Together with the optimization of regenerant consumption, Resinex ™ K-8 will allow you to obtain high quality process water economically. Resinex ™ K-8 is available in different particle sizes specially adapted for mixed bed and countercurrent applications.
