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.
Grade | Viscosity (1% sol.) | DS | pH | Key Applications |
---|---|---|---|---|
Textile/Paper | 50-5,000 mPa·s | 0.7-1.2 | 6.5-8.5 | Sizing, coating |
Oilfield | 500-5,000 mPa·s | 0.9-1.5 | 7.0-10 | Drilling fluids |
Construction | 100-3,000 mPa·s | 0.6-1.0 | 6.0-9.0 | Mortar water retention |
Detergents | 5-200 mPa·s | 0.4-0.8 | 6.0-11 | Thickener, anti-redeposition |
Paints/Ceramics | 1,000-10,000 mPa·s | 0.8-1.2 | 6.5-9.0 | Rheology modifier |
Applications & Dosage Recommendations
Use: Sizing agent, coating binder, dye thickener.
Dosage:
Textile Sizing: 1-3% (on fabric weight).
Paper Coating: 0.5-2% (improves smoothness).
Use: Fluid loss control, viscosifier.
Dosage: 0.5-2% in drilling mud (enhances borehole stability).
Use: Water retention, workability enhancer.
Dosage: 0.1-0.5% (reduces cracking in plaster/mortar).
Use: Rheology modifier, anti-settling agent.
Dosage: 0.2-1.5% (adjusts viscosity).
Use: Anti-redeposition agent, thickener.
Dosage: 0.1-0.8% (keeps dirt suspended).
Use: Binder, improves adhesion.
Dosage: 0.2-1.0% (enhances workability).
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).
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).
