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 |

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).
