Specification :

Polyanionic cellulose PAC 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.PAC-HV having the features of heavy molecular weight and Can better control the flowing characteristics of mud.With the characteristics of light molecular weight and thick molecular intensity.PAC-LV contributes to expand the osculating surface with substance Therefore, PAC-LV possesses the superiorities of water duty maintaining, acid resistance, temperature resistance and etc

Usage:
The product is used as an additive for drilling mud, especially used in drilling at the salt-rich aera or under the sea.
Package:
Packing The inner layer is polyethylene film bag. The outer layer is plastic woven bag or composite plastic woven bag. Net weight is 25kg per bag.
