ZGA455FD Macroporous Weak Base Anion Resin

Description

1. Description:

Hydrolite ZGA 455 FD is a weakly basic anion resin with a macroporous structure based on polystyrene. This product has a larger pore size and specific surface area, and is capable of adsorbing large organic molecules. The normal adsorption rate can reach 80-95%, and the elution rate exceeds 95%. Therefore, it is suitable for demineralization and colorization of sugar solutions. This product can also replace activated carbon for decolorization and purification of certain colored liquids, such as glycerin and glutamic acid, and the processing cost is lower than that of granular activated carbon.

ZGA455FD exhibits excellent mechanical strength, high exchange capacity, and a low swelling coefficient. It can be used in industries such as juices, beverages, and drinking water. It also removes salts and acids in the food industry to improve the color and flavor of products.

Note: ZGA455FD (ZG export product type) is D354FD (ZG domestic product type).
