  • Amphoteric paper dry-strength agent
    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".
  • Anionic paper Dry-strength Agent?
    Paper Dry-strength Agent is a kind of anionic multifunctional paper dry-strength agent, using aluminum sulfate as its retention agent. It can increase such indexes of the paper as tensile strength, bursting strength, and folding endurance and bring down the cost by a wide margin. Meanwhile, it has some synergistic effect of retention and filter-aid. Therefore, it is an excellent dry-strength agent applicable in the production of paper for packing and cultural uses.
