Is glyoxalated polyacrylamide a wet and dry-strengthening agent?

[DOI] [Google Scholar] 23.Yadollahi R., Hamzeh Y., Mahdavi H., Pourmousa S. Synthesis and evaluation of glyoxalated polyacrylamide (GPAM) as a wet and dry-strengthening agent of paper.

What are polymeric wet-strength agents?

Polymeric wet-strength agents are important additives used in the paper industry to improve the mechanical properties of paper products, especially when they come into contact with water. These agents play a crucial role in enhancing the durability, strength, and dimensional stability of paper products.

Can glyoxalated polyacryamide be used as a wet strength resin?

In this research we synthesized a series of wet strength resins based on glyoxalated polyacryamide (GPAM) under different reaction conditions using acrylamide, ethylenediamine and glyoxal as the main materials and their effects on wet and dry-strength papers was investigated.

What is polyacrylamide used for?

Polyacrylamides have wide range of industrial applications as well as paper industry. They are applied mainly as clarifiers, retention and paper strengthening agents.

Does polymer distribution affect mechanical properties of cationic polyacrylamide dry-strength resin?

Mihara and Yamauchi showed the effect of polymer distribution on mechanical properties of paper sheets containing various amounts of cationic polyacrylamide dry-strength resin by DMA analysis performed in the 100–300 °C temperatures range in vibration mode at various frequencies .

Can Apam be used as a dry strength agent in coir based paper?

This study explores the benefits of using Amphoteric PAM (aPAM) and Cationic PAM (cPAM) as a dry strength agent in coir based paper. The aPAM and cPAM were incorporated to coir pulp slurry in different dosages (0.5% – 2.0%) during stock preparation. Industrial grade of potassium aluminum sulfate (alum) was used for all sets handsheet.
