Dry Strength
BERSTRENGTH® 5040
This new innovative process for glyoxalated polyacrylamides (GPAM) eliminates using traditional, low solids (8-9%) and short shelf life (4-6 weeks) strength additives. The additive is prepared at the mill site from high solids content components to provide improved and uniform efficiency. Read more
BERSTRENGTH 5150
PAPER STRENGTH ADDITIVE FOR ON–SITE GLYOXALATION
This high solids, proprietary cationic polyacrylamide, is designed for mill-site crosslinking to provide highly effective dry strength and temporary wet strength improvement in recycled and virgin fiber systems. The freshly produced active polymer complex is easily retained on the cellulose fibers and its reactivity is further enhanced during the drying process. System chemistry is the same as the well proven conventional glyoxalated polyacrylamide strength additives. Read more
