Poly Anionic Cellulose (PAC-LV)
PAC-LV is a low-viscosity, high-purity Polyanionic Cellulose polymer designed for filtration control in water-based drilling fluids. It provides excellent fluid loss reduction without significantly increasing the rheology of the mud system. PAC-LV is effective in fresh water, seawater, brines, and KCl polymer mud systems.
