Mixed-bed Strongly Acidic
Styrene-based Cation Exchange Resin


001X7MB, aka 732MB is a uniform and premium grade strongly acidic cation exchange resin, which is applicable to softening and desalination in water treatment system. Its uniformity and particle size can be optimized accordingly by the operation of industrial water treatment equipment. 001×7MB combined with 201×7MB can be used in processing pure water and ultrapure water preparations in mixed bed system, whose properties are equivalent to IR-1000NA and S108.
