CT-CMC-HV Carboxy Methyl Cellulose Polymer High Viscosity

DESCRIPTION

CT-CMC HV is a high viscosity, high molecular weight dispersible Carboxy Methyl cellulose High Viscosity fluid loss additive designed to provide viscosity and reduce API filtration rate to water based drilling fluids.

APPLICATION

It is a cost effective additive used to reduce API filtration rate of many water based drilling fluids from freshwater to saturate saltwater. It is suited for water-loss and rheological control in low-solids mud and is a highly efficient viscosifier in all other mud

ADVANTAGES

• Widely available and low cost polymer for fluid Loss control

• It is an effective at providing filtration control in most water based drilling fluids.

• It is effective in low concentrations.

• It is Non–Toxic.

• It is not subjected to bacterial fermentation and calcium contamination.

• Can be used in Most water based Fluid systems

• Increases viscosity
