CMC is an important cellulose ether, It is obtained by chemical modification of natural fiber and is a polyanion compound with good water-solubility, easily soluble in both cold and hot water.
CMC plays important role of reducing water loss and increasing viscosity in drilling fluid, cementing fluid and fracturing fluid, so as to protect the wall, carry drill cuttings, protect the drill bit, prevent mud loss and improve the drilling speed. Add directly or with glue solution to mud, add 0.1-0.3 to fresh water mud and 0.5-0.8 to salt water mud.
Specifications

CMC is an excellent dispersant and adhesive, as well as a water-retaining agent capable of emulsifying. Due to these characteristics, it is widely used in the paper industry.
CMC in the paper making industry enables paper to have better characteristics and performance, especially for the process and painting with strict requirements and special needs of product, such as coated paper, matte paper, nano waterproof paper or other special papers and other types of paper. CMC cannot be replaced.

CMC is a special cellulose used as a thickener, binder, and suspending agent in toothpaste to create a stable, cohesive paste. It prevents separation of ingredients, provides a smooth texture, ensures the toothpaste maintains its shape on the brush, and offers good flowability for squeezing from the tube. Key properties include high water solubility, moisture retention, thixotropy (shear-thinning behavior), and compatibility with various toothpaste ingredients. 

CMC is a cellulose ether that is easily soluble in both hot and cold water, boasts the highest yield, and is the most versatile and convenient of all cellulose products.CMC is primarily used in the food industry, with a typical addition level of 0.2%-0.5%.Compared to other similar hydrophilic colloids, food-grade CMC exhibits strong acid and salt resistance, excellent transparency, low free fiber content, rapid dissolution, and excellent fluidity after dissolution.
As an excellent emulsifier, stabilizer, and thickener, food-grade CMC is widely used in the food industry in beverages, ice cream, yogurt, meat products, bread, wine, jelly, candy, biscuits, noodles, jam, and more.
