CPAM Medium Charge Density
Low-medium charge cationic PAM serves dual purposes — as a retention and drainage aid in paper making, and as a flocculant for light organic sludge. The moderate charge density provides good fiber retention without over-flocculating the pulp.

Frequently Asked Questions — CPAM Medium Charge Density
How does CPAM improve paper quality?
It retains fine fibers and fillers (calcium carbonate, clay) in the sheet, improving formation, reducing white water load, and increasing paper strength while lowering raw material costs.
What dosage for tissue paper?
0.02–0.05% based on dry pulp weight. Lower doses for hardwood kraft; higher for recycled fiber furnish with high fines.
