CMC–HV (High Viscosity Grade) is a high-purity, water-soluble anionic polymer derived from cellulose. It is designed for use in water-based drilling fluids where strong viscosity-building, fluid loss control, and rheology enhancement are required.
CMC-HV produces significantly higher viscosity compared to CMC-LV, while also offering excellent filtration control.
