Others: Paint Grade, Detergent-grade, Toothpaste-grade Paper-grade, Medicine-grade, Mining Grade Usage: 1. Oil drilling grade CMC used in fracturing fluid, drilling fluid and well cementing fluid as fluid loss controller and tackifier. It can protect the shaft wall and prevent mud loss thus enhance recovery efficiency. 4.CMC in Food Industry:CMC is widely used in frozen desserts, protein food, beverages, icings, dressings, instant noodles, etc. |

building grade cmc--carboxy mthyl cellulose Material |
Carboxymethyl Cellulose Sodium (CMC-Na) is a cellulose derivative obtained by chemically modificating the natural cellulose. It is one of the most important water soluble polymers with many advantages that other natural or synthetic glues do not have. CMC solution has good properties of thickening, adhering, emulsifying, and stabilizing. Membrane forming, moisture-holding, shape-holding, dispersing and anti-enzyme. The solution of CMC can be mixed with dissolvable animal glues, glycerin, sobbitol, Arabic gum, pectin, xanthic gum and dissolvable starch. |
