NINGBO INNO PHARMCHEM CO.,LTD is dedicated to providing innovative chemical solutions that drive efficiency and quality in the paper industry. One of our key offerings is cationic polyacrylamide (CPAM), a high-performance additive particularly effective as a retention aid. In the intricate process of papermaking, retaining fine fibers, fillers, and other additives is crucial for both product quality and economic viability. CPAM plays a vital role in achieving these objectives.

The effectiveness of CPAM as a retention aid stems from its unique molecular structure, which carries a net positive charge. This cationic nature allows it to strongly adsorb onto the predominantly negatively charged surfaces of cellulose fibers, fines, and fillers commonly found in paper pulp. When CPAM is introduced into the papermaking slurry, it works through a bridging mechanism. The long polymer chains adsorb onto multiple particles, creating stable flocs. These larger flocs are then more effectively trapped by the forming fabric, significantly increasing the first-pass retention rate.

Improved retention offers several tangible benefits. Firstly, it minimizes the loss of expensive raw materials like fillers and fine fibers into the white water system. This directly translates to lower production costs for paper manufacturers. Secondly, by retaining more material in the sheet, CPAM contributes to better paper uniformity and improved optical properties such as brightness and opacity. The enhanced formation achieved with CPAM also leads to better printability and a more consistent product.

In addition to retention, CPAM also contributes to improved drainage. The flocculation action that enhances retention also helps to create a more porous structure within the forming sheet, allowing water to drain more freely. This leads to faster machine speeds and reduced energy consumption during the drying process.

NINGBO INNO PHARMCHEM CO.,LTD’s CPAM is designed for optimal performance across a range of papermaking conditions. Our commitment to quality ensures that the product is consistent and reliable, enabling paper mills to achieve predictable and superior results. By incorporating CPAM into their wet-end chemistry, paper manufacturers can achieve significantly higher retention rates, leading to improved efficiency, reduced costs, and higher quality paper products. This makes CPAM an indispensable tool for modern papermaking operations seeking competitive advantages.
