Rel-Pac® XL – Dry Polyanionic Cellulosic Polymer

CETCO Rel Pac Xtra Low

For use in fresh & salt water systems as a more efficient filtration control additive

Rel-Pac® Xtra-Low is a low viscosity, non-fermenting dry polymer that helps increase borehole stability by lowering filtrate and fluid loss more effectively than other Pacs.  Rel-Pac® Xtra-Low helps control reactive formations by reducing available water and controls unconsolidated formations by reducing whole fluid loss.


  • Highly dispersible
  • Controls filtration rates and helps form a thin flexible wall cake
  • Only moderate viscosity increase for increased flow
  • Stabilizes many types of drilled formations
  • Available in 2 lb. or 50 lb. bags
