Carboxy Methyl Cellulose Low Viscosity CMC-LVT API-13A
CMC is available in a variety of viscosity grades. Low-viscosity CMC (CMC-LV) offers excellent dispersion, stabilization, colloidal protection, and film-forming properties.
High-viscosity CMC (CMC-HV) demonstrates exceptionally high thickening efficiency, along with superior water retention, suspension stability, and rheology-modifying characteristics.
CAS No.: 9004-32-4
Formula: C6H12O6
EINECS: 618-326-2
Description
CMC-LVT is a low-viscosity, technical-grade, dispersible Carboxymethyl Cellulose fluid loss additive designed to reduce API filtration rate with minimum increase in viscosity in water based drilling fluids.
Application
CMC-LVT is a cost-effective additive used as a fluid loss reducer in fresh water and brackish water systems. It is used to control fluid loss in dispersed and non-dispersed drilling fluids.
Advantage
1. Widely available and low-cost polymer for fluid loss control.
2. Effective at providing filtration control in most water-based drilling fluids.
3. Effective in low concentrations.
4. It is non-Toxic.
5. It is not subject to bacterial fermentation and calcium contamination.
6. Can be used in most water-based fluid systems.
