Polyacrylamide resins are suitable for near-neutral papermaking conditions. The resins can be set only with a small amount of alum complex. Dry paper strength resins can improve selected paper properties, including the bursting strength and ring crush strength.
Dry paper strength resins enhance bursting strength and ring crush strength for industrial paper.
