Dual Bed Gel Strong Acid
Styrene Series Cation Exchange Resin


001X7DB, aka 732DB is a gel-type strongly acidic styrene-based cation exchange resin with a sulphonic acid functional group, synthesized by special technology. Characterized by its excellent physical and chemical stability, this resin functions with good thermostable performance.

With its additional fine selectivity and high exchange capacity, this model is primarily used in the precise cationic dual-bed water treatment system for ultrapure water preparation within various industries.
