DRISPAC® Plus Polymer

Drispac® Plus Polymers are high-quality Polyanionic cellulose polymers. They are used for inhibition, water-loss control and viscosity in water-based muds. Drispac® Plus Polymer comes in two viscosity grades: regular (high viscosity) and Superlo® Polymer (medium viscosity). The highly dispersible Drispac® Plus Polymer resists the formation of "fisheyes," even under the poorest mixing conditions and may be added rapidly to the system if desired.


  • NSF certification
  • Controls fluid loss
  • Promotes fragile gels
  • Inhibits hydratable, swelling shales
  • Increases resistance of clay mud to contamination
  • Non-fermenting, no preservative needed
  • Good thermal stability ≥ 300 °F in most water-base drilling fluids
  • Produces thin, slick, tough filter cake
  • Environmentally compatible
  • Retards drilled solids build-up by inhibiting cuttings disintegration
  • Eliminates fisheyes in the mud
  • Reduces friction and can reduce ECD
  • Works well on rigs with poor mixing facilities
  • Works well at any salinity
