DuPont™ AmberLite™ HPR1200 Na Ion Exchange Resin For Industrial Softening Applications

DuPont™ AmberLite™ HPR1200 Na is a high-performance, uniform particle size, gel-type strong acid cation exchange resin designed for industrial softening applications. It delivers excellent operating capacity and rinse characteristics while reducing chemical regenerant and rinse water usage. Compatible with all major system technologies. Ideal for industrial water softening and demineralization where the sodium form is preferred. Formerly sold as DOWEX MARATHON™ 1200 Na.
