ZGA 451-Z macroporous strongly acidic styrene series cation exchange resin

Description

1. Description

Hydrolite ZGA 451-Z is a cationic exchange resin containing a sulfonic acid group (-SO₃H) in a styrene-diethylenebenzene copolymer with a macroporous structure. It is used in low- and medium-pressure condensate treatment systems together with ZGA 353-Z, a medium-pressure mixed anionic exchange resin. It is characterized by a more uniform granule distribution, excellent hydraulic properties, mechanical stability, and antioxidant capacity.
