Sodium Carboxy Methyl Cellylose (CMC)

Technical or Industrial Grade

Sodium carboxymethyl cellulose (CMC) is a cellulose derivative, an ionic cellulose gum, and owing to its unique thickening, suspending, adhesion, and water retention properties, is widely used in various industrial fields.

According to the different purity, Sodium carboxymethyl cellulose is in the appearance of white or yellowish powder and soluble in cold and hot water.

Sodium carboxymethyl cellulose is divided into a variety of models depending on the degree of substitution, solution viscosity and the purity.

Heating Sodium carboxymethyl cellulose solution, the viscosity of Sodium carboxymethyl cellulose decreases with increasing temperatures.

As long as the temperature does not exceed 50 ℃, this effect is reversible, because kept at higher temperatures for a long time, the alkaline substances in the solution can cause the degradation of Sodium carboxymethyl cellulose.

Grades of CMC

Sodium carboxymethyl cellulose is generally divided into 3 grades depending on the purity:

* Food high-purity grade (with a content more than 99.5%)

* Industrial grade (with a content more than 90%)

* Crude products (with a content more than 65%
