The main indicators for measuring the quality of carboxymethylcellulose na are the viscosity, degree of substitution (D.S) and purity. We divide na carboxymethyl cellulose into two types, type 6 and type 9 based on D.S value. Type 6 is common CMC (D.S 0.75-0.9), and type 9 (D.S more than 0.9) is acid-resistant with much better stability.
Fortune Biotech, as one of the cellulose gum suppliers , we provide cmc chemical china and etc. It is China's pioneer in Carboxymethyl Cellulose (CMC) production and a council member of the China Cellulose Industry Association.
