Glyoxalated Polyacrylamides G-PAM: additives for enhancing

Summary: Glyoxalated polyacrylamides (G- PAM) provide an alternative chemistry to other papermaking resins additives for wet and dry strength. This new generation of G-PAM provides a better compromise between wet end chemistry performance and paper dry strength targets along with logistical benefits of shipping concentration and shelf life.

Polyacrylamides (PAMs) are used to increase the dry strength of papers by hydrogen bonding. PAM of molecular weight of 100,000 to 500,000 is used at about 0.5% on pulp and also acts as a retention aid. It is sometimes used to allow increased use of lower quality pulps such as secondary and hardwood fiber.
