732FG is a food grade gel-type strongly acidic cation exchange resin of the sulphonated polystyrene type. It has excellent physical and chemical stability and thermostable performance. Structured with condensed porosity and quite intense granular strength, 732FG performs extra high exchange capacity and excellent adsorbability with inorganic cations of metal salts and nonmetal minerals, such as metal cations K+, Ca2+, Mg2+ or nonmetallic ammonium NH4+. This premium resin model is thereby most suitable for hardness removal or water softening for demineralization system and industrial pure-water preparations.
In regard to typical combined applications in traditional drinking water and food fermentation industries, 732FG is often coupled used with D201FG for demineralization and refining purposes. Specifically metal cations are removed while some positive organics remain for further refining needs or when decoloring is not absolutely demanded. Meanwhile acids radicals as well as negative organics of color and odor are subject to D201FG's chemical macropores to be captured and released.
732FG therefore has been widely used for desalting, refining and softening in food &beverage, medicine &pharmaceuticals and sugar manufacturing industries. Particularly in the deionizing and decoloring process of water preparations for drinking water and fermented &processed food, D201FG co-functions well with removing medium-acid radicals plus negative organic molecules of color and odor from organic solutions as starch sugar, beer, sorbitol, xylitol, amino acid, citric acid, lactic acid and the like.
