High-quality PAC fluid loss control polymer POLYPAC UL polyanionic cellulose (PAC) is a high‐quality, water‐soluble polymer designed to control fluid loss. Since it is an “ultra‐low” (UL) additive, POLYPAC UL causes a minimal increase in viscosity in water‐base muds. Applications POLYPAC UL additive controls fluid loss in freshwater, seawater, KCl and salt muds. It […]

POLYPAC R polyanionic cellulose is a high‐quality, water‐soluble polymer designed to control fluid‐loss and increase viscosity in water‐base muds. This protective polymer “envelope” inhibits the dispersion of shale cuttings and restricts fluid interactions with exposed shales. POLYPAC R additive controls fluid‐loss in freshwater, seawater, KCl, and salt muds. It forms a thin, resilient, low‐permeability filtercake […]
