Floating Bed Gel-type Strongly Acidic
Styrene-based Cation Exchange Resin

PRODUCT DATA SHEET:

001X7FB, aka 732FB is a gel-type strongly acidic styrene-based cation exchange resin with sulphonic acid functional groups, synthesized by special technology. Characterized by its excellent physical and chemical stability, this resin functions with good thermostable performance.

For its extra fine selectivity and high exchange capacity, 001X7FB model is primarily placed within the cation-bed, one of the two exchange columns where raw water enters first, followed by the other anion-bed that is often filled with 201X 7FB model. Both columns are placed in parallel with raw water reverse flowing into so as to form a composite floating bed backflushing water-processing system for precise demineralization, pure-water &ultrapure water preparation within various industries.
