Products Description
Cationic polyacrylamide (CPAM) is produced in large-scale manufacturing facilities using standardized production processes under ISO quality management systems. Each batch can be supplied with a certificate of analysis, and sample testing is supported to verify performance before bulk purchasing, ensuring product suitability in advance. The stable quality and transparent testing system make procurement safer and more reliable.
Cationic polyacrylamide (CPAM) is a linear polymer with positively charged functional groups (such as quaternary ammonium groups) on its molecular chain, enabling strong electrostatic adsorption with negatively charged pulp fibers and fillers. It appears as a white granular or powder material, easily soluble in water, non-toxic, and non-corrosive.
In the papermaking industry, CPAM can be used as a dry-strength agent, retention aid, and drainage aid, significantly improving paper quality, reducing costs, and increasing production capacity. As an efficient drainage and retention aid, it directly interacts with inorganic salts, fibers, and other organic polymers through electrostatic bridging, enhancing paper strength, reducing fiber and filler loss, and improving drainage efficiency.

Frequently Asked Questions (FAQ)
Q: 1. What is the main function of cationic polyacrylamide in papermaking?
A: CPAM plays three main roles in papermaking: as a dry strength agent to improve paper strength, as a retention aid to increase retention of fine fibers and fillers, and as a drainage aid to accelerate dewatering of pulp. Through electrostatic adsorption and bridging effects, it binds negatively charged fibers, fillers, and additives together.
Q: 2. How to select molecular weight and ionic degree?
A: Molecular weight: Recommended range is 6–12 million for papermaking additives. Too high molecular weight may affect dispersion, while too low may reduce strengthening performance.
Ionic degree: 20%–40% is recommended for dry strength agents; 30%–50% for retention and drainage aids. Excessively high ionic degree may affect sizing performance.
Q: 3. What is the recommended dosage?
A: Dry strength agent: 3–10 kg per ton of oven-dry pulp
Retention aid: 0.5–2 kg per ton of oven-dry pulp
Actual dosage should be determined through lab testing based on paper grade, pulp characteristics, and process conditions.
Q: 4. How to properly dissolve and use the product?
A: Prepare a 0.1%–0.5% aqueous solution; neutral or deionized water is preferred
Add the product slowly and evenly into stirring water to avoid "fish eyes"
Stir for about 60 minutes until fully dissolved
Add at the fan pump inlet or after the pressure screen to ensure proper mixing with pulp
The prepared solution should be used within 24 hours
Q: 5. What precautions should be taken during use?
A: Avoid direct mixing with anionic chemicals to prevent precipitation
Water temperature should not exceed 50°C to avoid thermal degradation
Stirring speed should be controlled (100–300 rpm) to prevent polymer chain breakage
Store in a cool, dry place to prevent moisture absorption and caking
Q: 6. Can CPAM be used with other papermaking chemicals?
A: Yes, it can be used with cationic starch, sizing agents, etc. However, compatibility with anionic chemicals (such as anionic PAM or CMC) must be carefully evaluated through lab testing before use.
Q: 7. What is the shelf life of the product?
A: The product has a shelf life of 2 years under cool and dry storage conditions. Prepared solutions are recommended to be used within 24 hours to avoid performance loss.
Q: 8. Which paper strength properties can CPAM improve?
A: CPAM dry strength agents significantly improve tensile strength, burst strength, folding resistance, and ring crush strength. It also enhances smoothness and printability of paper.
