Product Description
Sodium Carboxy Methyl Cellulose(CMC)is synthesized by the alkali-catalyzed reaction of cellulose with chloroacetic acid. The polar (organic acid) carboxyl groups render the cellulose soluble and chemically reactive. The functional properties of Fooding Carboxy Methyl Cellulose(CMC) depend on the degree of substitution of the cellulose structure (i.e., how many of the hydroxyl groups have taken part in the substitution reaction), as well as the chain length of the cellulose backbone structure and the degree of clustering of the carboxymethyl substituents.

Product performance and characteristics:
CMC has a high ability to control water loss. In particular, PAC is a highly effective fluid loss reducer at lower dosages. You can control the loss of water to a higher level. It does not affect other properties of the mud.
The formed mud cake is of good quality, strong and tough.
It has good temperature resistance and excellent salt resistance. Under a certain salt concentration, it still has a good ability to reduce water loss and maintain a certain rheology. Compared to soluble in salt water and soluble in water, the viscosity hardly changes. Particularly suitable for offshore drilling and deep well requirements.
It can well control the rheological properties of the mud. It has good non-Newtonian fluidity.
In addition, KELAIDE® CMC is used as a cementing fluid to prevent fluids from entering pores and fractures. It is used as a fracturing fluid to control fluid loss into the well.
