Polyphosphate Dispersant (Talc & Pitch Control)
Polyphosphate-based dispersants are used in papermaking to stabilize mineral slurry dispersions (calcium carbonate, kaolin, talc) and to control pitch and stickies deposition on paper machine surfaces. They prevent agglomeration of mineral particles in coating colors and filling slurries, ensuring uniform dispersion and stable viscosity. They also act as scale inhibitors for calcium carbonate deposits in white water systems.
