  • What are the applications of non ionic polyacrylamide?
  • Three major applications have become established: retention, water treatment (from save-all to effluent plant) and as a dry strength resin. Non-ionic polyacrylamides, although somewhat effective as retention aids, are essentially non-substantive to fibres.
  • What is polyacrylamide used for?
  • Since the original introduction of polyacrylamides, considerable development has taken place, and their use is now regarded as standard in most mills. Three major applications have become established: retention, water treatment (from save-all to effluent plant) and as a dry strength resin.
  • Are polyacrylamide resins cationic?
  • The early anionic polyacrylamide resins are still widely used, both in powder and liquid form. The natural anionic charge on cellulose fibres, and the contaminants commonly found in papermaking systems, led researchers to seek methods of putting a cationic charge on these chemicals, thus making them more substantive to fibres.
