Product Description

Product Description

 

Product Name:
Sodium Carboxymethyl Cellulose (CMC) - High-Performance Water-Soluble Polymer for Industrial Applications
 

Description:
Our industrial-grade Carboxymethyl Cellulose (CMC) is a versatile cellulose ether derived from natural wood pulp, engineered to deliver superior thickening, binding, water retention, and stabilizing properties. With customizable viscosity (50-50,000 mPa·s) and degree of substitution (DS: 0.4-1.5), it is ideal for demanding industrial processes.

Application

Applications & Dosage Recommendations

 

1. Textile & Paper Industry

• Use: Sizing agent, coating binder, dye thickener.

• Dosage:

  • Textile Sizing: 1-3% (on fabric weight).

  • Paper Coating: 0.5-2% (improves smoothness).
     

2. Oilfield Drilling Fluids

• Use: Fluid loss control, viscosifier.

• Dosage: 0.5-2% in drilling mud (enhances borehole stability).
   

3. Construction (Cement & Mortar)

• Use: Water retention, workability enhancer.

• Dosage: 0.1-0.5% (reduces cracking in plaster/mortar).
   

4. Paints & Coatings

• Use: Rheology modifier, anti-settling agent.

• Dosage: 0.2-1.5% (adjusts viscosity).
   

5. Detergents & Cleaners

• Use: Anti-redeposition agent, thickener.

• Dosage: 0.1-0.8% (keeps dirt suspended).
   

6. Ceramics & Tile Adhesives

• Use: Binder, improves adhesion.

• Dosage: 0.2-1.0% (enhances workability).

Package and storage

 

• Packaging:

  • 25 kg woven PP bags (with inner PE liner for moisture protection).

  • 500 kg / 1 MT jumbo bags (FIBC, palletized).
     

• Storage:

  • Keep in a dry, cool place (humidity <60%, temperature 10-30°C).

  • Shelf life: 2 years (unopened).

 

FAQ

 

Q1: What is the difference between low- and high-viscosity CMC?
- Low-viscosity (5-200 mPa·s): Used in detergents, where flowability is key.
- High-viscosity (1,000-50,000 mPa·s): Ideal for oilfield fluids and paints.
 

Q2: Can CMC replace synthetic thickeners like PVA?
- Yes, in many applications (e.g., textiles, coatings), but test for compatibility.
 

Q3: How does CMC improve mortar performance?
- It retains water, preventing rapid drying and reducing shrinkage cracks.
 

Q4: Is CMC resistant to high temperatures?
- Up to 80°C for most grades; oilfield CMC can withstand 120°C+.
 

Q5: What packaging options are available?
- 25 kg bags (standard) or bulk FIBC bags (500 kg/1 MT).
