Bulk Density and Particle Size of Sodium CMC

The bulk density and particle size of sodium carboxymethyl cellulose (CMC) can vary depending on factors such as the manufacturing process, grade, and intended application. However, here are typical ranges for bulk density and particle size:

1. Bulk Density:

• The bulk density of sodium CMC can range from approximately 0.3 g/cm³ to 0.8 g/cm³.
• Bulk density is influenced by factors such as particle size, compaction, and moisture content.
• Higher bulk density values indicate greater compactness and mass per unit volume of CMC powder.
• Bulk density is measured using standard methods such as tapped density or bulk density testers.

2. Particle Size:

• The particle size of sodium CMC typically ranges from 50 to 800 microns (µm).
• Particle size distribution may vary depending on the grade and production method of CMC.
• Particle size can affect properties such as solubility, dispersibility, flowability, and texture in formulations.
• Particle size analysis is performed using techniques such as laser diffraction, microscopy, or sieve analysis.

It’s important to note that specific values for bulk density and particle size may vary among different grades and suppliers of sodium carboxymethyl cellulose. Manufacturers often provide detailed specifications and technical data sheets outlining the physical properties of their CMC products, including bulk density, particle size distribution, and other relevant parameters. These specifications are important for selecting the appropriate grade of CMC for a particular application and ensuring consistent performance in formulations.
