Sodium Carboxymethyl
Carboxymethyl Cellulose Sodium, Carboxymethyl Cellulose, shortly CMC, used as additive in different field,CMC has the fuctions of thickening ,suspending,emulsifying, stabilizing ,shaping, filming,bulking, etc. It can replace the application of guar gum,gelatin and pectin.It is widely used in modern various industry,such as food, oil drilling, paper making, detergent ,ceramic grade etc.
Dynacel® Paper Making Grade CMC, it is higher valued by the majority of paper engineers and is widely used in the production of paper and paperboard, such as paper and paperboard coating process, coating rheology modifier, water - retention agent, film-forming agent, auxiliary adhesives, wet end retention enhancers and surface sizing agents, grinding aids, filler modifier and the flocculating agent which used in waste water treatment etc. We have different paper making grades of CMC to meet the different customers’ requirements.
