ZGC258FD Food Grade Resin

 

"Hydrolite" ZGC 258FDis a sort of cation exchange resin that has carboxylic acid group (-COOH) in the acrylic acid copolymer with macroporous structure. As a macroporous weak acid cation resin, it has great exchange capacity, fast exchange speed and with good mechanical strength.

ZGC 258FD is especially suitable for removing bicarbonate, carbonate and other basic salt species in water.Mainly filled in small exchange equipments for household and community water treatment to desalination and softening of water.
