Sodium Carboxymethyl Cellulose is applicable to the following industries.
Due to water-solubility, film making ability and binding characteristic, CMC is being used in sizing of yarns in warping. Also, CMC with high viscosity levels are used in printing fabrics; either with sodium alginate or replacing it.
In oil industry, CMC is being used together with barite bentonite, and clay in order to prepare drilling muds, which helps controlling suspension, and getting out the sand in the drilling process.
Glue and Adhesive Industry:
By making use of water solubility and binding properties, CMC is used as glue for wallpaper applications, and is also used in leather industry too.
CMC is used in paper industry for binding the ingredients, and for increasing the strenght of paper. Some purified and technical grades are also used for smoothing the surface of paper, which means better printability and quality.
It is used in paints to control the flow property of paints.
CMC can be used with plaster and cement. The main objective is to prevent early freezing; that way, it becomes quite easy to work on plaster in a longer period.
CMC is used in detergent industry widely due to its property of getting the dirt particules with the rinsing water. In cream detergents, it prevents the drying of surface and CMC can hold the water (moisture) for a long time.
