ANTISOL™ PAC Polymers for

Water Based Drilling Fluids

Antisol™ Polyanionic Cellulose (PAC) Polymers is a carboxymethylcellulose additive proven indispensable when modifying flow and filtration properties in water-based drilling fluids. This water-soluble anionic polymer derived from cellulose has viscosity ranges from extremely high to ultra-low, making Antisol™ grades an extremely versatile additive for many industrial applications. It can be used to create thickening, stabilizing, emulsifying, suspension and water-binding characteristics when used alone or combined with other components. 

Benefits of using ANTISOL™ in Drilling fluids
  • Effective dispersion of clay particles
  • Low surface tension reduces foaming under shear
  • Retention of water of the drilling fluid, aiding in penetration into the formation
  • High heat stability making it suitable for geothermal drilling
  • Thixotropic behavior results in efficient removal of cuttings and reduces friction at drill bit
Grade Viscosity Value Proposition
FL 30000 min 2500 mPa*S Excellent viscosifier, shale inhibiting properties
FL 100 80-160 mPa*S Ideal rheological properties for low filtrate values
PAC ULV 30 25-100 mPa*S For extremely low filtration values, Negligible effect on viscosity
