Cationic glyoxalated polyacrylamide Glyoxalated polyacrylamide (GPAM) is widely applied in a variety of paper grades to increase paper dry strength. GPAM is typically added in the pulp suspension before paper sheet formation. Upon drying the treated paper sheet, GPAM is believed to form covalent bonds with cellulose to increase paper dry strength.

Enhancements on Glyoxalated Polyacrylamide Technology
Traditionally glyoxalated polyacrylamide (GPAM) technology is applied to pulps with acidic pH to ensure optimal dry/wet strength development. Increasing papermaking pH or residual sulfite concentration in the wet end often has a detrimental effect on GPAM performance.
FENNOBOND 3300E – UNIQUE GPAM STRENGTH RESIN Cationic glyoxalated polyacrylamide (GPAM) is a well-known strength resin [1-2] that is often regarded as a benchmark for generating dry strength. GPAM is a reactive polymer that can covalently bind with cellulose upon dehydration as shown in Fig. 1. The result is a
New Dry Strength Technology for Weight Reduction
BASF has recently introduced a novel glyoxalated polyacrylamide (GPAM) dry strength technology that features a point of use manufacturing process. This technology combines unique starting materials with a new approach to product generation that results in twice the number of fiber reactive groups per pound, when compared to conventional GPAM
