Carboxymethyl Cellulose (CMC) Powder

Properties:

Carboxymethyl Cellulose (CMC) is a white and flowing fine powder. It is a cellulose derivative obtained by chemical modification the natural cellulose. Carboxymethyl cellulose is one of the most important water-soluble polymers with many advantages that other natural or synthetic glues do not have.

Carboxymethyl cellulose powder is tasteless, smells mold-proof, non-toxic, non-flammable, and easily dissolved in water.

Carboxymethyl cellulose solution is a transparent viscose solution. This solution has good thickening, adhering, emulsifying, and stabilizing properties. Membrane forming, moisture-holding, shape-holding, dispersing, and anti-enzyme.

Carboxymethyl cellulose solution can be mixed with dissolvable animal glues, glycerin, sorbitol, Arabic gum, pectin, xanthic gum, and dissolvable starch.

Uses:

CMC oil drilling grade is used in fracturing, drilling, and well-cementing fluid as a fluid loss controller and tackifier. Carboxymethyl cellulose can protect the shaft wall and prevent mud loss, thus enhancing recovery efficiency. CMC has the following characteristics.

• Excellent water retention even at low concentrations.
• Excellent thickening effect.
• Good resistance to salt and temperature change.
• It Imparts excellent rheological properties.

Packing:

Packed in multiple paper bags or fiber drums (25KG), or as per customer requirement, keep dry.

Synonyms:

CMC chemical, CM cellulose, CMC polymer, carboxy methylated cellulose.
