With our vast industrial experience, we are indulged in manufacturing, exporting and supplying a quality array of Carboxy Methyl Cellulose in Shijiazhuang, Hebei, China.

Product Description:
CMC appears to be white or light yellow powder, which is odorless and non-toxic. It is soluble in cold or hot water. When it solutes, some colloidal solution will appear, which is neutral or slightly alkaline. The important feature of CMC is that it can form colloid solution with high viscosity. Many factors influencing its viscosity are concentration, PH, temperature, substituted ratio and salts, etc.
