The market taxonomy of Dry Strength Resins for Paper Making further subdivides by type into four dominant chemistries: polyacrylamide (PAM), polyvinyl alcohol (PVA), starch‑based resins, and polyethyleneimine (PEI). Polyacrylamide, comprising roughly 35% of the type mix, offers superior flocculation control and is favored in high‑speed tissue and packaging lines. Polyvinyl alcohol, at about 30%, provides excellent film‑forming capability and water resistance, making it suitable for printing & writing grades. Starch‑based resins, representing close to 25%, are valued for their renewable profile and cost efficiency, often deployed in specialty and eco‑focused paper products. Polyethyleneimine, the smallest segment at roughly 10%, delivers high cationic charge density, enhancing dry strength in niche industrial papers where aggressive bonding is required. Each resin type contributes uniquely to the total market volume by matching its physicochemical properties with the performance criteria of specific paper applications.
