PAC LV is low-viscosity polyanionic cellulose (PAC) offered by our company, used as a fluid-loss control additive for drilling mud. PAC LV has low molecular weight which is essentially not a viscosifier.
Advantages:
Effective in controlling fluid loss
Resists attack from bacteria, requiring no preservatives or bactericide
Environmentally acceptable
Depending on water quality, provides viscosity
