Polyanionic cellulose PT PAC

PT PAC (fluid loss control additive). PT PAC is a Polyanionic cellulose polymer that is available in both regular viscosity (R) grade as well as a medium-viscosity (LV) grade.


– Fluid-loss control (0.3 to 9.0 kg/m3)
– Inhibition/encapsulation (2.0 to 9.0 kg/m3)
– Improved filter cake (1.5 kg/m3)
– Improved and Stabilized Rheology (2.0 to 3.0 kg/m3)


– Works at any salinity
– Control fluid loss
– Inhibits hydrateable, swelling shales
– Increases resistance of clay muds to contamination
– Retards drilled solids build-up by inhibiting cutting disintegration
– Produces thin, slick, tough filter cake
– Non-fermenting, no preservative needed
– Reduces friction and frequency of differential sticking
– Increases carrying capacity
