In the papermaking industry, papermaking polyacryalmide plays a vital role in improving process efficiency, fiber retention, drainage, and overall paper quality. Among the most commonly used types are cationic polyacrylamide (CPAM) and anionic polyacrylamide (APAM). While both serve as highly effective flocculants and retention aids, they differ significantly in molecular structure, ionic nature, and application behavior within various paper formulations.

Key Differences Between CPAM and APAM in Papermaking

Aspect	Cationic Polyacrylamide (CPAM)	Anionic Polyacrylamide (APAM)
Ionic Charge	Positive (Cationic)	Negative (Anionic)
Preferred Use	Acidic to neutral pH paper systems	Neutral to alkaline pH paper systems
Primary Function	Retention aid, dewatering enhancer	Flocculant for white water clarification
Interaction with Materials	Bonds well with negatively charged fibers	Works with positively charged fillers
Fiber Retention	Highly efficient in fine particle retention	Moderate, often used in secondary steps
Application Stage	Wet end (headbox), thickening	Water treatment, white water recovery

Application Considerations

Choosing the right type of polyacrylamide depends on several factors, such as the composition of the pulp slurry, the pH of the system, and the operational goals of the mill. CPAM is often used in fine paper or specialty paper applications requiring excellent retention and strength properties. In contrast, APAM is better suited for improving drainage and clarifying white water in larger-scale or recycled paper systems.

In some high-efficiency paper mills, a dual-polymer system is adopted, where both cationic and anionic types are dosed sequentially to balance fiber retention and water clarity—without compromising machine speed or product quality.
