Paper dry-strength agent(amphoteric)

Overview

Paper dry strength agent is polyacrylamide Series dry strength agent, with a higher molecular weight and cationic charge, widely using in packing paper (corrugated cardboard, kraft paper, etc.), cultural paper and other paper , especially for paper making systems with more anionic impurities or the high concentration of electrolyte. It can effectively improve the dry strength of paper,  the physical properties of paper. At the same time, It also can keep and bond small fibers and filler, reducing fiber loss and reducing the "wool off". It can produce enough dry strength of the fiber ,allowing the use of low-cost raw materials or a higher proportion of secondary fiber.
