A well-designed wet-end chemical program can help paper mills improve fiber and filler retention, optimize drainage, reduce material losses, and maintain consistent sheet quality. A Cationic Paper Making Retention Additive works through electrostatic interactions and polymer-assisted particle retention, helping mills manage fine fibers and mineral fillers during paper formation. Ewooan supplies this specialized papermaking chemical for manufacturers seeking more stable production processes and improved resource utilization. This guide explains its working principles, key benefits, application considerations, and selection criteria for industrial paper production.

As a professional papermaking chemical manufacturer with an annual production capacity of over 50,000 tons, Ewooan has launched the industry-leading AKD sizing Promoter, a third-generation core cationic polymeric synergistic additive perfectly designed for neutral-to-alkaline AKD sizing systems.

Polyacrylamide is a water-soluble polymer. Featuring flocculation and thickening properties, it is widely used in wastewater treatment, papermaking, mineral processing, coal washing and oilfield sectors. It has four grades: cationic, anionic, nonionic and amphoteric, with distinct performances for different working conditions. Selection should be based on water quality, pH, treatment goals and product specifications. Jar tests help confirm the proper type and dosage. Proper product selection and dosing deliver efficient solid-liquid separation, sludge dewatering, retention and drainage improvement in papermaking. It cuts chemical consumption and keeps industrial systems running stably.

Ewooan, the leading specialized industrial chemical manufacturer with an annual production capacity of over 50,000 tons of water treatment products, has developed the high-performance Cationic Polyacrylamide Industrial Flocculant that delivers industry-leading flocculation results far exceeding traditional inorganic flocculant performance.
