Strong Acid Cation Ion Exchange Resin, Macroporous Structure

Description

Strong Acid Cation (SAC) Ion Exchange Resin, macroporous type, is a sulfonated copolymer of styrene and divinylbenzene manufactured with a macroporous matrix. The permanent pore structure provides enhanced resistance to fouling, superior physical stability, and improved performance in applications involving high organics or strong oxidizing agents. Compared to gel-type SAC resins, macroporous versions have slightly lower exchange capacity but are preferred in demanding water treatment, process, and catalytic applications due to their robustness and durability.

Applications

• Industrial water softening in systems with organic or iron fouling potential

• Demineralization and deionization with high organic load

• Condensate polishing in power generation plants

• Wastewater treatment with variable quality feed water

• Food and beverage processing with higher organic contamination risk

• Hydrometallurgy and mining water circuits

• Catalysis support (acidic ion exchange catalysis)

• Chemical process streams requiring fouling-resistant cation exchange

Key Features

• Macroporous matrix with permanent pore structure

• Excellent resistance to organic fouling and oxidants

• High mechanical and osmotic stability

• Long service life under harsh operating conditions

• Broad application range including water, wastewater, and process catalysis
