CMC (Sodium Carboxymethyl Cellulose)

CMC (Sodium Carboxymethyl Cellulose)

Characteristics

・One of the most widely distributed water soluble polymer derived from cellulose
・There are various grades depending on viscosity (due to molecular weight) and DS(Degree of Subsititution).
・CMC is an anionic structure and is affected by contamination with metal irons and salts. This effect differs according to the viscosity and DS. CMC is less easily affected as the DS decreases and reacts ・CMC is readily soluble in water and give suitable viscosity (Thickener).
・CMC had high dispersibility and prevents sedimentation of partiｃles (Dispersion stabilizer).

ＣＭＣ DAICEL grade line up

Grades of CMC Daicel are determined mainly by viscosity of 1% aqueous solution and by Degree of substitution, which indicates the strength of the CMC structure. We provide various grades from extremely high to low viscosity, so that you can choose suitable grades to your application. Grades that comply with official regulations and standards are also available. Please contact us for more details
