Broke Repulping and Disintegration Aid
Broke repulping and disintegration aids are alkaline or enzymatic chemical formulations that accelerate the breakdown of wet-strength-treated, sized, or coated broke paper in repulping systems. They facilitate fiber separation and reduce energy consumption in broke pulpers, ensuring efficient recovery of fiber for reuse in the paper machine furnish. These aids are particularly important for tissue, paperboard, and specialty paper mills that generate wet-strength or coated broke.
