ZGCD552 Macroporous strongly acidic cation exchange resin

Description

PRODUCT DESCRIPTION ZGCD552

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

FEATURES AND ADVANTAGES

● MACROPOROUS STRUCTURE

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

● FINE FRACTION, LOW PRESSURE DROP

95% of the pellets are within the specified range, which ensures lower pressure drop.

● EXCELLENT CHEMICAL AND PHYSICAL STABILITY

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