Main features：
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.
Packing :
Stored in dry, cool airiness place, far away from heat, avoid insolation, sign with no moisture and no insolation
Packing: plastic woven bag with Peliner.N.W.25kg.
