PUROLITE® SST60H resin offers lower leakages at all regenerant levels and better metals removal, is less susceptible to fouling, promotes shorter regeneration cycles and lower rinse water requirements and is more resistant to oxidation. The non-solvent sulfonated resin features an inert inner core that significantly reduces chemical leakage. Ion exchange occurs only in the outer shell of the resin beads.www.purolite.com
