CMC (LVG/HVG)
PZT-CMC-LV is offered in low-viscosity (LVG) and high-viscosity (HVG) grades of standard sodium carboxymethyl cellulose - the same cellulose-ether chemistry as PAC but with a lower degree of substitution and purity. LVG grade controls fluid loss with minimal added viscosity, while HVG grade is dosed specifically to add significant viscosity. The dual-grade flexibility lets a mud engineer choose the right tool for the job from one chemical family, at lower cost than PAC, with a long, well-understood performance track record in freshwater bentonite systems.

Use Cases & Applications
- Fluid-loss control (LVG) and viscosity building (HVG) in freshwater WBM
- Cost-effective standard-duty alternative to PAC in less demanding wells
Pros
- Cost-effective for freshwater systems
- Predictable, well-documented dosing behavior
- Compatible with standard bentonite systems
Cons & Limitations
- Poor tolerance of divalent ions (calcium/magnesium) and high salinity - flocculates and loses efficiency
- Lower thermal stability than PAC
- Needs a higher treatment level than PAC for equivalent fluid-loss control
CMC-LV (Low Viscosity)PZT-CMC-LV
Standard-grade, low-viscosity CMC delivering fluid-loss control with minimal added viscosity, at CMC characteristic lower cost versus PAC.
CMC-HV (High Viscosity)PZT-CMC-HV
Standard-grade, high-viscosity CMC providing both fluid-loss control and meaningful viscosity build in freshwater WBM at lower cost than PAC.
