Advantages of the product

Superior Retention and Drainage Enhancement

Our cationic polyacrylamide for paper mill is designed with high charge density and optimal molecular weight, enabling exceptional adsorption onto negatively charged pulp fibers and fillers. This strong electrostatic interaction significantly improves first-pass retention of fine fibers and inorganic fillers, such as calcium carbonate and clay. By minimizing the loss of valuable raw materials in the white water circuit, paper mills experience reduced raw material consumption and lower wastewater treatment load. Moreover, the polymer’s bridging mechanism accelerates water drainage on the forming wire, increasing machine speed and productivity.

Enhanced Paper Strength and Quality

Beyond retention, our cationic polyacrylamide for paper mill acts as a dry strength additive, improving the internal bond strength and tensile properties of paper and board. The polymer’s cationic groups interact with anionic fiber surfaces, forming ionic bonds that increase fiber-to-fiber bonding. This results in stronger paper, allowing mills to use higher percentages of recycled fibers or lower basis weights without sacrificing performance. Enhanced strength translates to fewer paper breaks during printing, converting, and packaging operations, reducing downtime and waste.

Sustainable and Cost-Effective Solution

Feymer’s cationic polyacrylamide for paper mill aligns with the industry’s push towards sustainability and cost reduction. By improving retention and drainage, our product reduces the amount of fresh water needed, lowers energy consumption in drying, and minimizes the discharge of solids into wastewater. This not only lowers operational costs but also helps mills meet environmental regulations. Additionally, our efficient polymer allows for higher use of recycled fibers, reducing the demand for virgin pulp and conserving natural resources.

In the modern paper manufacturing landscape, the use of cationic polyacrylamide (CPAM) has become indispensable for optimizing wet-end chemistry and ensuring efficient production. Cationic polyacrylamide for paper mill applications plays a pivotal role in enhancing fiber retention, improving drainage, and increasing paper strength. The mechanism of action is rooted in its cationic charge, which electrostatically binds to anionic components in the pulp suspension, including cellulose fibers, fines, and fillers like calcium carbonate and talc. By forming bridges between particles, CPAM flocculates them into larger aggregates that are more easily retained on the forming fabric. This leads to higher first-pass retention values, which directly translate to reduced raw material usage and lower load on the water treatment system.

Frequently Questions

How does cationic polyacrylamide improve retention in paper mills?

Cationic polyacrylamide (CPAM) improves retention by promoting the flocculation of pulp components. In the wet-end of a paper machine, pulp consists of fibers, fines, fillers, and various dissolved and colloidal substances. Most of these components carry a negative surface charge when dispersed in water. CPAM, being positively charged, is attracted to these negative surfaces and can bridge several particles together, forming larger flocs that are more easily retained on the forming fabric. This process significantly increases first-pass retention, meaning a greater percentage of the solids remain in the sheet rather than passing through into the white water.
Yes, cationic polyacrylamide is versatile and can be used in various papermaking processes, including those producing fine paper, newsprint, tissue, and board. Its application is beneficial in any system where retention, drainage, or strength enhancement is desired. Different grades of CPAM are available with varying molecular weights and charge densities, allowing customization to specific furnish and machine conditions.

Customer Testimonials

John Smith
Exceptional Retention and Cost Savings

We have been using Feymer’s cationic polyacrylamide in our paper mill for over a year, and the results have been outstanding. Our first-pass retention improved by 15%, leading to significant savings in fiber and filler costs. The drainage on our wire has improved as well, allowing us to increase machine speed by 8%. The product is easy to dissolve and handle, and the technical team provided excellent support during the initial trials. This CPAM has truly optimized our wet-end chemistry and contributed to our bottom line.

Maria Garcia
Improved Strength with Recycled Fibers

As a mill that heavily relies on recycled fibers, we faced challenges with paper strength and runnability. Since switching to Feymer’s cationic polyacrylamide, we have seen a marked improvement in both tensile and burst strength of our finished products. This enabled us to reduce basis weight by 5% without compromising quality, saving on material costs. Additionally, the product helped control pitch deposits, reducing downtime and maintenance. Feymer’s responsive technical service made the transition seamless. I highly recommend their CPAM for any mill looking to enhance performance.
