ZGC258FD acrylic based macroporous weakly acidic cationic exchange resin containing carboxyl groups

Description

PRODUCT DESCRIPTIONZGC258FD is an acrylic-based, macroporous, weakly acidic cation exchange resin containing carboxyl groups. It can be used in applications such as water softening, dealkalization, demineralization, and chemical treatment. It is ideal for softening water with high TDS and special applications such as treating aqueous organic solutions and selectively separating heavy metal cations. It can be used for the isolation and purification of biochemical and pharmaceutical substances, as well as in food processing. ZGC258FD has a high working capacity for divalent cations and very high regeneration efficiency. This resin is available in hydrogen (H) form or sodium (Na) form for special applications.

FEATURES AND ADVANTAGES

CARBOXYL FUNCTIONAL GROUPS: Provide very high regeneration efficiency and high working capacity.
UNIFORM PARTICLE SIZE, LOW PRESSURE: 95% of the granules are within the specified range, resulting in low pressure.
HIGH CHEMICAL AND PHYSICAL STABILITY: 90% sphericity, together with low expansion, macroporous structure, high fracture strength and uniform particle size provide great resistance to particle breakage due to mechanical, thermal or osmotic loads.
