Pure-grade filtration control additive
A polyanionic polymer used as a pure-grade filtration-control additive manufactured exclusively for M-I SWACO for use in water-base drilling fluids. This high-quality polymer is a modified starch that will control fluid loss in a wide variety of drilling fluids with minimal increase in viscosity. THERMPAC UL starch is an “ultra-low” additive that generates less viscosity than regular-viscosity products.
