PAC, short said for Polyanionic Cellulose, is a water-soluble cellulose ether derivative, which is made from natural cellulose by chemical modification and an important type of water-soluble cellulose ether. It comes in the shape of white to yellow powder or particles, PAC is tasteless, nontoxic, strong in hygroscopicity and freely soluble in cold and hot water.
Our product contains better heat-resistant stability, salt tolerance and strong antibacterial activity. When slurry or fluid prepared from the product; it gives better fluid loss reducing capability, rejection capability and higher temperature tolerance.

This product which has usage in different industries as in:-
The sodium salt of Polyanionic Cellulose widely used in petroleum drilling, especially in salt well and offshore oil drilling.
Drilling mud is suspended matter of solids in aqueous solution and the same as other colloidal suspension dispersion. Polyanionic Cellulose may keep it stable and increases life period.
The drilling mud with Polyanionic Cellulose can form thin and solid shaft wall as well as filter cake with low permeability and it may reduce hole shrinkage and collapse phenomena.
Polyanionic Celloluse is seldom affected by mycete, so it does not need to maintain high PH value or use preservatives. It can still keep stable with the corresponding decrease of the usage amount of other chemical agents or ever within a certain range of temperature variation at the time of the drilling process.
Following industries use Polyanionic Cellulose on a regular basis:-
