Sodium Carboxymethyl Cellulose (also referred as CMC and Carboxy Methyl Cellulose) can briefly be described as an anionic water-soluble polymer produced from naturally occurring cellulose by etherification, substituting the hydroxyl groups with carboxymethyl groups on the cellulose chain.

Application

There are a number of parameters which define the properties of the Sodium Carboxymethyl Cellulose CMC.
√ Purity (active CMC content): inevitably CMC powder is produced with by products that are sodium salts which comes in the product Sodium Carboxymethyl Cellulose content in the product is the purity.
√ Viscosity: one of the most interesting characteristics of the CMC powder is the viscosity which can be from low to high. It is measured mostly by digital viscometers at certain temperatures in different solution rates; such as 1%, 2% or 4%.
√ Degree of Substituion: is the average number of sodium carboxymethyl groups per anhydroglucose unit on the cellulose back bone. This parameter in some application areas is quite important to control in the product.
√ Physical form: the CMC powder can be produced in fine powder to dust-free granule.

 Function

Thanks to its versatility, CMC can provide different functions and that is what it owes for being used in a range of industries.
√Solubility
√Rheology
√Adsorption on surfaces
These main characteristics help our CMC provide control over properties of the aqueous systems by establishing effects of
√ Thickening
√ Binding
√ Film forming
√ Stabilizing
√ Protective colloid
√ Water retention
√ Thixotropy
