Advantages of the product

Superior Retention and Filtration Efficiency

Feymer’s paper mill cationic PAM dramatically improves the retention of fine fibers and fillers during sheet forming. By employing a high molecular weight and optimal charge density, our polymer effectively bridges particles and neutralizes anionic trash, resulting in increased first-pass retention. This leads to significant reductions in raw material consumption and energy usage for drying. Paper mills experience cleaner filtrates and lower chemical loads in backwater systems, enhancing water loop closure and environmental compliance.

Enhanced Drainage and Increased Production Speed

Drainage is a critical bottleneck in papermaking, and our cationic PAM acts as a powerful drainage aid, accelerating water removal on the wire. By flocculating fines and improving fiber pad permeability, our polymer significantly reduces water retention time, allowing faster machine speeds and increased throughput. In tests, paper mills have reported up to 20% higher drainage rates without compromising sheet quality. This advantage enables you to maximize production capacity with existing equipment, lowering specific energy consumption per ton of paper.

Robust Dry Strength and Better Sheet Quality

Beyond retention and drainage, our paper mill cationic PAM significantly contributes to the dry strength of the final sheet. The electrostatic interactions and hydrogen bonding between the polymer and cellulose fibers enhance inter-fiber bonding, increasing burst, tensile, and tear strength by up to 15% in many applications. This allows you to use lower basis weights or cheaper fillers while maintaining the same strength specifications, reducing costs and environmental footprint.

Emulsion Anionic Polyacrylamide (APAM)

In the demanding environment of a paper mill, every additive must deliver measurable value in terms of quality, efficiency, and sustainability. Cationic polyacrylamide (PAM) has emerged as a cornerstone of modern papermaking chemistry due to its versatility and performance. Feymer’s paper mill cationic PAM is a high-molecular-weight, water-soluble copolymer of acrylamide and cationic monomers, carefully synthesized to provide optimal balance between molecular weight and cationic charge. This unique design ensures effective neutralization of anionic contaminants commonly found in pulps—especially those from recycled fibers or high-yield processes—and strong flocculation of fine particles. When introduced into the thin stock before the headbox, the polymer adsorbs onto fibers and fillers, bridging them into larger flocs.

Frequently Questions

What is the optimal dosage for paper mill cationic PAM?

The optimal dosage of Feymer paper mill cationic PAM varies based on your specific system conditions, such as pulp type, conductivity, pH, and the level of anionic trash. Generally, dosages range from 100 to 500 grams per ton of dry pulp. For best results, we recommend conducting a jar test to determine the ideal point where retention and drainage are maximized without over-flocculation that could impair formation. Overdosing can lead to excessive flocculation, causing poor sheet formation and increased chemical costs. Underdosing may result in incomplete retention and slower drainage. Our technical team can assist you in conducting on-site trials and optimizing dosage using our advanced analytical tools.
Absolutely. Feymer paper mill cationic PAM is especially designed to handle systems with high anionic demand, such as those encountered when using recycled pulp, denkled pulp, or high-yield mechanical pulps. The polymer’s high cationic charge density allows it to neutralize anionic trash effectively, reducing their interference with other papermaking additives like dyes, sizing agents, and wet-strength resins. This results in more stable retention and drainage performance. In recycled fiber systems, where fines and contaminants are abundant, our product improves fine fiber retention and reduces the load on the water treatment system.

Markus Weber
Revolutionized Our Retention and Reduced Costs

Switching to Feymer’s paper mill cationic PAM has been a game-changer for our packaging mill. We immediately noticed a significant improvement in first-pass retention—by about 25%—which cut our fiber and filler consumption dramatically. Because the drainage increased, our machine speed went up by 12%, boosting daily production without any major investment.

Sustainable and Cost-Effective Operational Gains

Sustainable and Cost-Effective Operational Gains

Choosing Feymer’s cationic PAM goes beyond immediate performance boosts; it delivers tangible sustainability and profitability benefits. By improving retention and drainage, our product directly reduces the consumption of pulp, fillers, and energy. For a typical 100,000 tonne per year mill, even a 5% increase in retention can save over 5,000 tonnes of raw materials annually, translating to substantial cost savings. Enhanced drainage reduces steam consumption in the dryer section, lowering your factory’s carbon footprint and energy bills. Improved closure of the water loop means reduced fresh water intake and lower effluent treatment costs, easing compliance with environmental regulations. Furthermore, our polymer’s exceptional performance allows papermakers to increase the proportion of recycled fibers, circumventing raw material price volatility and aligning with the circular economy.
