PDAC is a water-soluble cationic polymer that is indispensable in the pulp and paper industry. Its primary role in a paper mill is to improve fine particle retention, accelerate drainage, and enhance strength through electrical charge neutralization and interphase bridging. Addressing anionic trash accumulation in closed water loops, Feymer's PDAC forms larger flocs to maximize efficiency and reduce effluent load, supporting sustainable production.
