ZGCD650 Macroporous Strong Acid Cation Exchange Resin

Description

ZGCD650 PRODUCT DESCRIPTION

As a catalyst in hydrolysis reactions such as the hydrolysis of esters, cane sugar and polysaccharides.

FEATURES AND ADVANTAGES

● Meets FDA requirements for use in drinking water.
Complies with 21 CFR 173.25 of the Food Additives Regulations
of the F.DA

● MACROPOROUS STRUCTURE

The unique macroporous structure significantly increases service life and ensures high resistance to mechanical and osmotic stress.

● UNIFORM PARTICLE SIZE, LOW PRESSURE DROP

95% of the granules are within a certain size range, which ensures lower pressure drop.

● EXCELLENT CHEMICAL AND PHYSICAL STABILITY

The macroporous matrix provides excellent resistance to granule breakdown and oxidation.

APPLICATION

ZGCD650 Macroporous Strong Acid Resin is suitable for various water treatment methods, such as softening, desalination, and wastewater treatment. It offers a long service life when treating aggressive waters, such as condensate, chlorinated water, and waters with high temperatures or flow rates.

ZGCD650 is used in conjunction with weakly acidic cation exchange resin in cationic double beds and in pure and ultrapure water processes.

ZGCD650 with macroporous structure is used as a catalyst in many chemical processes due to its high kinetics, large surface area and corresponding porosity.
