Used as a viscosity builder and fluid loss reducer in all water-based drilling fluids.

Prevents the dispersion of shale and clay cuttings in water-based muds.

Used to maintain wellbore diameter stability.

Due to its high molecular weight, it may cause an instantaneous increase in viscosity.

Vispol-PW Polymer is sensitive to calcium contamination and high pH; therefore, the maximum calcium concentration should not exceed 400 ppm and the pH should not exceed 11.
