Paper Industry
The high speed of paper machines requires the support of retention and drainage technology. Polyacrylamide could improve the retention rate of fiber and filler, and improve the drainability of paper stock. Polyacrylamide could also act as a sizing agent during paper making. It could improve the water proof feature of paper to increase persistence and shelf life. As it could form a dense film with fiber, the film has fine water proof features and prevents the water seep into the paper. For cationic polyacrylamide with low molecular weight, it could act as a dispersant to improve the uniformity of paper.
