Advantages of the product

Exceptional Retention and Drainage Enhancement

Our PAM for paper mill retention is engineered with high molecular weight and tailored charge density to maximize fiber and filler retention. By promoting rapid flocculation, it significantly reduces the loss of valuable fines and fillers in the forming section, leading to improved first-pass retention. This enhanced retention not only boosts paper strength and opacity but also reduces the load on the water treatment system. The polymer’s unique architecture ensures that it performs efficiently across a wide range of pH values and shear conditions, making it adaptable to diverse papermaking processes.

Tailored Solutions for Every Paper Type

Recognizing that every paper mill has unique requirements, we offer a comprehensive portfolio of PAM products—from anionic and cationic to non-ionic formulations—each meticulously designed for specific furnish compositions and end-use applications. For fine paper production, our high-charge cationic PAMs optimize filler retention, whereas for board and packaging grades, our high-molecular-weight anionics enhance fiber bonding. We also provide emulsion and dry forms to suit your handling and dosing systems. Our technical specialists analyze your mill’s water chemistry, machine configuration, and furnish to recommend the most effective PAM grade.

Sustainable and Eco-Friendly Performance

Our PAM for paper mill retention aligns with our mission: “Making Every Waterprint Count.” By enhancing retention, our product minimizes the discharge of suspended solids and organic matter, thus significantly reducing pollution load. This facilitates easier compliance with stringent environmental regulations and supports your sustainability goals. Additionally, improved retention means less fresh fiber and filler required, reducing forest resource consumption. Our PAM is designed to be highly efficient, requiring lower dosages compared to conventional aids, which lowers chemical footprint and cost.

Retention is a critical parameter in paper manufacturing, impacting both paper quality and production economics. In the intricate process of forming a sheet, fine fibers, fillers, and other additives must be retained while water is drained efficiently. Poor retention leads to higher raw material consumption, reduced productivity, and increased load on water treatment systems. Polyacrylamide (PAM) has emerged as a highly effective retention aid due to its ability to flocculate suspended particles and attach them to the fiber network. As a leading water treatment chemical provider, Jiangsu Feymer Technology Co., Ltd. has developed a specialized line of PAM for paper mill retention that delivers superior performance across diverse papermaking conditions. Our products feature precisely controlled molecular weights and charge densities to achieve optimal flocculation without interfering with other process additives.

Frequently Questions

How does PAM for paper mill retention improve retention and drainage?

PAM (polyacrylamide) functions as a flocculant and retention aid by bridging particles and microfibers. High molecular weight PAM molecules have long chains that can attach to multiple suspended solids—including fiber fines, fillers like calcium carbonate, and pigments—creating flocs that become incorporated into the paper web as it forms. This flocculation action dramatically increases first-pass retention: fewer valuable components are lost to the white water, which reduces raw material costs and chemical oxygen demand in the circulating water. Additionally, larger flocs dewater more efficiently. As a result, water drains faster on the forming table, which translates into higher machine speeds and reduced energy demand in the drying section.
We offer a comprehensive range of PAM formulations to meet diverse papermaking needs. Our portfolio includes cationic PAMs (non-ionic, anionic, and amphoteric types). Cationic PAMs are particularly effective in retaining anionic fillers and fines, making them ideal for fine paper production. Non-ionic PAMs are useful in mechanical pulp applications and where low charge interference exists. Anionic PAMs are best for neutral and alkaline papermaking due to reduced hydrogen bonding interference. Amphoteric PAMs provide balanced charge interaction and excel in high shear conditions. We also provide emulsion and powder forms, allowing flexibility in handling and addition systems.

Customer Testimonials

Markus Hansen
Exceptional Retention Improvement

We switched to Feymer’s PAM for our fine paper machine, and the results were outstanding. First-pass retention jumped from 68% to over 80%, and our white water clarity improved significantly. We actually reduced our total chemical costs by 15% because we could lower the use of other additives. The product is easy to handle and feed, with no viscosity issues. Feymer’s technical team stayed with us throughout the trial and provided clear guidance on dosage. I highly recommend their PAM for paper mills seeking performance and sustainability.

Alicia Fernandez
Superior Service and Consistent Quality

We have been using Feymer’s PAM for retention on our recycled paper mill for over a year. The product quality has been consistent, leading to stable machine operations and fewer breaks. Our sheet ash content is now predictable, and we’ve seen a decrease in deposits on press rolls. What sets Feymer apart is their responsiveness and technical expertise—they are always available to troubleshoot or optimize our program. This partnership is invaluable for our competitiveness.

Advanced Polymer Design

Advanced Polymer Design

At Feymer, we have leveraged our expertise in functional monomers and water-soluble polymers to create PAM for paper mill retention with superior flocculation properties. Our advanced polymer design includes precise control of molecular weight, charge density, and structural architecture. For instance, our cationic PAM features high charge density with optimized molecular weight to ensure effective charge neutralization and bridging, even in high-conductivity white water systems. We use proprietary production techniques, including controlled radical polymerization, to achieve narrow molecular weight distribution, which improves performance consistency and reduces chemical sludge formation. This design translates to significant improvements in first-pass retention, drainage, and overall paper quality, as verified by extensive mill trials. The polymers are engineered to dissolve rapidly without lumping, ensuring uniform addition and maximum efficacy.
AI-Enhanced Process Optimization

AI-Enhanced Process Optimization

Our PAM for paper mill retention is complemented by our AI-empowered water treatment technologies. We integrate smart sensors and advanced analytics to monitor critical parameters like retention efficiency, drainage rate, and water turbidity in real-time. Our platform uses machine learning algorithms to predict optimal PAM dosage based on process variations, minimizing manual adjustments and errors. This data-driven approach ensures that our customers achieve peak retention performance consistently while reducing chemical waste. For example, a closed-loop control system can automatically increase or decrease the PAM flow rate as paper furnish changes, maintaining excellence without operator intervention. With years of data from numerous installations, our AI models continuously improve, becoming more accurate over time. Additionally, our technical team uses this data to fine-tune our polymer recommendations for each mill, ensuring synergy between chemistry and control.
