Polyanionic Cellulose All Grade
Poly Anionic Cellulose (PAC) has a wide range of application and can be applied to all application fields of CMC.


Physicochemical Properties

Poly Anionic Cellulose 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.

a) High Degree of Substitution: The D.S value is 0.85 to 1.4.

b) Thermal stability :

-Its aqueous solution performs stable under 80 °C. when the temperature is close to 150 °C, it can still displayed a certain viscosity for about 48hours.

c) Salt,Acid and Alkalis resistance :

-PAC has a stable performance when PH value ranges from 3 to 11 and can be applied in various kinds of extremely harsh conditions.

d) Good Compatibility:

-Be compatible with other cellulose ethers, water soluble gum, softeners, resins, etc;

-Gradually show oil-soluble when its D.S value exceeds 1.2.

e) Good Solubility :

--Be quickly dissolved in cold or hot water by using simple stirring equipment.

--PAC dissolves faster in hot water.

--Instant dissolve type PAC can fully dissolved in a few minutes, it greatly improves the usage convenience and producing efficiency.

f) Good Stability :

-Aqueous solution of PAC has light stability, a longer guarantee -Strong anti-bacterial properties without fermented.

g) Extreme Low Usage Amount:

-For its high stability and high degree of substitution, the usage amount of the PAC only equivalent the 30% to 60 % of the Carboxy Methyl Cellulose (CMC) in the same using conditions. It reduced the company's cost by a certain extent. -ith high economic and social benefits for its advantage of high cost-effective and the saving of consumption of raw materials.

h) Green and environmental-friend

-Its main raw material is refined cotton

-With no pharmacological effect

-Physiologically harmless and its producing process is environmentally friendly.

i) Deep well drilling operation

Poly Anionic Cellulose(PAC) can be used foroil drilling operation at high temperature in deep well.
