CMC since 2010

CMC (Sodium Carboxymethylcellulose) is the universal thickener for industrial applications and various tasks.

Linguang CMC is well known for premium quality grades since decades.

Due to the big series of different CMC derivates we cannot present all CMC types here.

Viscosifier - Filtrate Control Additive

PAC-R is a modified natural polyanionic cellulosic polymer (PAC). It is exhibits high viscosity and is readily dispersible and water soluble. PAC-R provides filtration control in bentonite-based drilling fluids and increases water absorption capacity. Optimal results will be obtained by using PAC-R as an additive to the Phrikolat sodium Bentonite Type W.

Applications:

Horizontal Directional Drilling (HDD), Water Well Drilling, Vertical & Oil Field Drilling, Pipe Jacking

Properties:

• Improves filter cake properties of bentonite muds
• Provides filtration control in fresh or salt water muds
• Increases water absorption capacity
• Improves flow properties of most drilling fluids
• Minimizes torque and circulating pressure
• Acts as protective colloid for bentonite
• Reduces swelling and dispersion of drilled clay/cuttings
• Promotes bore hole stability in water sensitive formations
• Effective in small quantities
• No biocides or preservatives required

PAC-R is compatible with all bentonites & additives and does not contain any harmful ingredients.

Recommended Concentrations:

Added to bentonite muds: 0,5-1 kg/m³

To stabilize Water sensitive formations: 2-4 kg/m³

Using a high shear jet-type mixer (venturi) is highly recommended. PAC-R should always be added to the system after bentonite. Adding should be done slowly and uniformly to the entire circulating system. Salt water may require twice as much PAC-R as fresh water.

Packaging:

25 kg multiple paper-bags on pallet, shrink wrapped, 1000 kg per pallet

Big Bags à 1000 kg (on request)
