Product Performance and Characteristics 
1. The CMC for drilling mud allows borehole wall to form a thin but rigid filter cake with low permeability. Also, it helps reduce fluid loss.

2. After addition of CMC, mud allows a drilling rig to obtain low initial get strength and also decrease frictional force.

3. The gas wrapped in mud is apt to be released. Fragments are easily transported to mud. Additionally, great suspension and dispersion performance can extend the service life of mud.

4. Mildew affects very little mud prepared with the drilling mud ingredient. There is no need to retain high pH value or use a preservative.

5. The drilling fluid additive allows mud to offer great stability and outstanding salt-tolerant performance. With a certain concentration of salt, it can still provide superb fluid loss reducing capacity, even if the temperature reaches above 120℃.

As a China-based drilling mud fluid CMC manufacturer and supplier, our company offers a broad range of products that includes HPMC for building materials, hydroxyethyl cellulose for toothpaste, oil drilling PAC-HVT, and more.
