Dry-Strength Resins and Additives

DRY-STRENGTH ADDITIVES. Composition: The term "dry strength additives" refers to a variety of water-soluble polyelectrolytes. The term "dry strength resin" is most often used in connection with anionic copolymers of acrylamide. Acrylamide polymers, including amphoteric products (with both anionic and cationic groups), are commonly used in Japan.

The main function of Dry Strength Resins is to increase strength per unit of bonded area between fibers in any sheet of paper. Dry strength additives are usually polymers of acrylamide - anionic, cationic and amphoteric. Using OPL DSR makes it possible to achieve strength goals while maintaining higher dewatering rates and lower density of paper.

In addition to improving the dry strength characteristics of paper and board, the use of these additives can improve retention and dewatering and reduce deposition, which can contribute to improved machine runnability and sometimes allow for increased production when running at higher speeds.
