Paper dry strength agents are multifunctional chemicals which are extensively used to improve paper, tissue, and paperboard strength such as tensile, compressing, bursting, and internal bond and also to improve retention and drainage. They provide strength quality to paper products and also improve machine productivity and process efficiency. Paper dry strength agents are available in various types such as polyvinylamine, polyacrylamide, glyoxylated polyacrylamide, starch based polymers, amphoteric polymer, and others. Furthermore, increasing in demand of paper industry is likely to drive the paper dry strength agent market growth.
