Characteristic
Polyanionic cellulose is white or yellowish powder that is odorless and non-toxic. It is soluble in water to form thick liquid. It has good heat-stability and high resistance to salt. It is not fermented. Polyanionic cellulose (PAC) is a sodium carboxymethyl cellulose with high uniformity, high degree of substitution and high quality.
Usage
The product is used as an additive for drilling mud, especially used in drilling at the salt-rich aera or under the sea.
Packing
็ญhe inner layer is polyethylene film bag. The outer layer is plastic woven bag or composite plastic woven bag. Net weight is 25kg per bag. |
