  • What are the different types of paper strength additives?
  • When used as paper strength additives PAMs can be cationic (CPAM), glyoxalated (GPAM) (temporary wet-strength agent), anionic (APAM) or amphoteric polyacrylamide (AmPAM) (Wang et al. 2018 ). APAMs are considered to be good strength enhancers especially for recycled fibres (Ichiro, Yamauchi 2008 ).
  • How do cationic and anionic polymers increase bursting strength?
  • Substantial gain in breaking length and bursting strength were achieved through the sequential addition of cationic and anionic polymers. Many different synthetic and natural chemical additives are used in the manufacture of paper for a variety of different reasons during the wet formation process.
  • Do polymers increase paper strength?
  • Paper strength increased considerably when polymers are adhered on fibers in large amounts. Substantial gain in breaking length and bursting strength were achieved through the sequential addition of cationic and anionic polymers.
  • Is polyvinylamine a paper strength additive?
  • An emerging additive during the last decade is polyvinylamine (PVAm), which will impart both wet and dry strength to papers (Pelton 2014 ). Paper strength additives are typically cationic polymers with very high molecular weights, they adsorb to anionic fibres in a process driven by the entropic gain of counter ions being released (Wågberg 2000 ).
