Product Description

PAC appears to be white or light yellow powder, which is odorless and non-toxic. It's soluble in cold or hot water. when it solutes, some colloidal solution will appear, which is neutral or slightly alkaline. the important feature of PAC is that it can form colloid solution with high viscosity, many factors influencing its viscosity are concentration, PH, temperature, substituted ratio and salts, etc. 

Performance and characteristics of PAC:
PAC products are divided into two kinds that are with high viscosity(HV) and low viscosity(LV). It owns high purity, high substitution degree and the distribution of its substituent group is even, etc. It appears as white and fluxible powder. Its water solution is transparent sticky liquid. It can dissolve quickly in cold or hot water. It can be used as thickener, rheology control agent, adhesives, stabilizing agent, protective colloid, suspending agent and water retention agent.

PAC Advantages:
PAC has good heat stability, salt resistance and antimicrobial resistance. As the mud fluid formulated by PAC has good fluid loss, suppression, high temperature resistance, PAC is widely used in oil drilling, especially in salt water wells and offshore oil drilling.


1. High degree of substitution: The D.S value is 0.85-1.4.

2. Thermal stability: Its aqueous solution performs stable below 80°C. When the temperature is close to 150°C, it can still show a certain viscosity for about 48h.

3.Salt, acid and alkalis resistance:
PAV has a stable performance when PH value ranges from 3-11, and can be applied in various kinds of extremely harsh environments.

4. Good miscibility: It is compatible with other cellulose ethers, water-soluble gums, softeners, resins, etc.;
  Gradually shows oil-soluble when its D.S value exceeds 1.2

5. Good solubility: It can be quickly dissolved in cold water and hot water with simple stirring equipment; hot water dissolves faster; instant PAC can be fully dissolved in a few minutes, greatly improving the convenience of use And production efficiency.

6. Good stability: 
PAC aqueous solution has light stability, longer shelf life; strong anti-bacterial properties without fermented.

7. Extremely low usage amount:
For its high stability and high degree of substitution, the usage amount of PAC only equivalent the 30% to 60% of carboxy methyl cellulose (CMC) in the same using conditions. It reduced the company's cost by a certain extent. 

8. Green and environmental- friendly
The main raw material of polyanionic cellulose (PAC) is refined cotton, which has no pharmacological effect, physiologically harmless and its producing process is environmentally friendly.

9. Deep well drilling operation
Polyanionic cellulose can be used for oil drilling operations at high temperature in deep well.

PAC application for oil field 




PAC can be used in the drilling industry for fluid loss additives, thickener, etc.
The drilling mud is the suspended matter of solids in the aqueous solution, and the same as other colloidal suspension dispersions, so has a certain life period. Polyanionic Cellulose can keep it stable and then prolong its life period. It has more obvious effects especially in mud suspension dispersions with dissolving salt.
The drilling mud with Polyanionic Cellulose can form thin and solid shaft wall as well as filter cake with low permeability, and thus can reduce the hole shrinkage and collapse phenomena resulting from water loss of mud.
The mud with the addition of Polyanionic Cellulose is seldom affected by mycete, so it doesn't need to maintain high pH value or use preservatives. It can still keep stable with corresponding decrease of the usage amount of other chemical agents, or even within a certain range of temperature variation during the drilling process.
The mud with Polyanionic Cellulose regular enables the drilling machine to obtain low initial gel strength, so the mud can discharge air in it easily and discard debris in a mud pit quickly.
PAC-HV applies to the mud with smaller proportion and a small usage amount can increase viscosity and reduce fluid loss. A small amount of Polyanionic Cellulose can replace a lot of clay and this kind of mud can reduce the difficulties resulting from encountering CaSO42H20 or CaSO4 salt belt during drilling process.
However, PAC-LV applies to the mud with larger proportion, can reduce the fluid loss but have little effect on the viscosity. In use, Polyanionic Cellulose should be dissolved in water to prepare the solution (usually 1/40-1/20) and then add into the mud. Polyanionic Cellulose can also be compounded with other chemical agents to add into the mud.
