How does the expansion ratio of 150-250 times affect the properties of this expanded graphite?
The expansion ratio of 150-250 times indicates the volume increase upon thermal expansion, resulting in the worm-like powder morphology. This ratio directly influences the bulk density and porosity of the expanded graphite, with higher ratios producing lower density material. The specific expansion behavior is a key specification for quality assurance.
What are the compatibility considerations for using 50 mesh expanded graphite in composite formulations?
The 50 mesh expanded graphite has a relatively coarse particle size and a worm-like morphology. These characteristics can affect dispersion in polymer matrices, potentially requiring higher shear mixing or longer processing times. The material is supplied as a carbon material without surface treatments, so compatibility depends on the specific matrix and processing conditions.
What is the recommended method for verifying the expansion ratio of this expanded graphite in the laboratory?
The expansion ratio of 150-250 times can be verified by heating a known volume or mass of the worm-like powder at controlled temperatures and measuring the volume change. The product is supplied as a 50 mesh powder in a 500 g package, and the expansion ratio should be confirmed against the specified range for quality control purposes.
Expanded Graphite, 50 Mesh, 500 g offers a 150–250x expansion ratio producing worm-like, powder morphology, suitable for research requiring high-porosity carbon structures. The 50-mesh sieve size ensures consistent starting particle dimensions for laboratory preparation workflows.
Positive
- High expansion ratio (150–250x): The expansion ratio of 150–250 times provides a large volume increase upon thermal treatment, enabling the formation of worm-like, highly porous graphite structures useful for adsorption, intercalation, and thermal insulation applications.
- Controlled 50-mesh particle size: The 50-mesh specification delivers a defined starting particle size distribution, reducing batch-to-batch variability and improving reproducibility in expanded graphite synthesis and characterization.
Trade-offs
- Powder handling precautions required: The worm-like powder form generates fine particles that may become airborne, necessitating use of fume hoods, dust masks, and anti-static equipment to prevent inhalation, contamination, or electrostatic discharge.
- Expansion ratio as a range: The specified expansion ratio of 150–250 times is a broad range; actual performance depends on processing conditions (temperature, heating rate), requiring users to calibrate and characterize each batch for precise applications.
