Polyanionic Cellulose PAC SL

It is widely used for making up water-based mud (drilling fluid) in oil drilling engineering. It can control the water loss in drilling process and prevent hole-wall collapsing, necking down, cone blocked and other accidents caused by drilling mud water loss. Added to the bentonite-based mud, it can control the viscosity of the mud. The mud processed by the CMC is azymous and low cutting force.
