ZGC107DQ is a gel-type, strongly acidic cation exchange resin. The polymer matrix consists of polystyrene cross-linked with 8% divinylbenzene (DVB).
ZGC107DQ has excellent physical and chemical properties. It features high exchange capacity, low pressure drop, and good chemical and physical stability.
Supplied in Na-form. It is used in water softening and desalination processes, pure and ultrapure water treatment, and in the fuel and energy complex, food, chemical, and pharmaceutical industries. It can be used in double- and floating-bed systems.
