Specialty Resin for
Borate Removal/Separation


KP-2023 is an ion exchange resin synthesized with special technology, specializing in removing Fluorinion. For its highly firm and solid structure, this resin performs with its high anti-osmotic efficiency and excellent mechanical &shock resistance as well as functions anti-pollution from organics. 

Owing to its special strong-base functional groups, KP-2023 performs strong adsorbability to free radicals of both strong and weak acids, peculiarly with affinity power to typical weak acid radicals as borate(BO33-). KP-2023 performs highest selectivity and exchange capacity with weak-acid radicals-borate anions when traces of cations and anions of salts impurities left in demineralization or deionization system, following the processing of reverse osmosis and EDI. Hence it is widely being applied in the process of water purification.
