Name: CMC(Carboxy Methyl Cellulose Sodium )
1.Property:
Carboxymethyl Cellulose Sodium (CMC-Na) is a cellulose derivative obtained by chemically modificating the natural cellulose. It is one of the most important water soluble polymers with many advantages that other natural or synthetic glues do not have.
CMC is white and flowing fine powder. It is tasteless, smelless, mould-proof, non-toxic, non-flammable and easily dissolved in water to become transparent viscose solution.
CMC solution has good properties of thickening, adhering, emulsifying, and stabilizing. Membrane forming, moisture-holding, shape-holding, dispersing and anti-enzyme. The solution of CMC can be mixed with dissolvable animal glues, glycerin, sobbitol, Arabic gum, pectin, xanthic gum and dissolvable starch.
2.Advantage:
1.High degree of substitution, good uniformity of substitution. 
2. High transparency, viscosity and water loss can be controlled.
3.Suitable for fresh water, sea water, saturated brine slurry.
4.Stabilize soft soil structure; prevent collapse of wall of a well.
5.Can improve mud-making volume, reduce filtration loss.
6. Has excellent performance in drilling of oil.
3.Usage:
Oil drilling grade CMC used in fracturing fluid, drilling fluid and well cementing fluid as fluid loss controller and tackifier. It can protect the shaft wall and prevent mud loss thus enhance recovery efficiency. It has the following characteristics:
- Excellent water retention even at low concentration.
- Excellent thickening effect.
- Good resistance to salt and temperature change.
- Imparts excellent rheological property.
4.Package and Storage:
Packed in multiply paper bags or fiber drums (25KG), or as per customer requirement; Keep dry
