Product Description

Product Description

 

 

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.

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).
