At NINGBO INNO PHARMCHEM CO.,LTD, we understand that the strength and durability of paper are critical performance indicators. High viscosity cationic polyacrylamide (CPAM) is a key additive that significantly contributes to these properties, making it invaluable in modern papermaking. This article delves into how CPAM enhances both the dry and wet strength of paper products.

The primary mechanism by which CPAM improves paper strength is through its ability to enhance inter-fiber bonding. As a high molecular weight polymer, CPAM molecules can adsorb onto fiber surfaces and create physical bridges between them. These bridges, along with the inherent hydrogen bonding capabilities of CPAM and cellulose fibers, create a stronger matrix within the paper sheet. This results in improved dry strength properties such as tensile strength, burst strength, and tear resistance. For applications requiring robust paper, such as packaging or industrial grades, this strength enhancement is crucial.

Furthermore, CPAM's molecular structure and its ability to interact with both fibers and fillers contribute to improved paper formation. Better formation, characterized by a more uniform distribution of fibers, leads to a more consistent distribution of stress across the sheet, further contributing to its overall dry strength.

While CPAM is primarily recognized for its dry strength benefits, its properties can also indirectly contribute to improved wet strength. By creating a more robust interfiber network and enhancing retention, CPAM can lead to a denser and more cohesive sheet. This can help the paper resist the effects of moisture and maintain a greater proportion of its dry strength when wet, compared to papers made without such additives.
