RFQ Checklist
- Target expansion volume (e.g., 200 ml/g, 300 ml/g)
- Required onset temperature (e.g., 160°C, 220°C)
- Particle size (mesh size) and carbon purity percentage
- Host material (e.g., PU foam, rubber) and required pH limits
Intercalated expandable graphite flakes for advanced, halogen-free flame retardants and industrial thermal management.
Complete RFQs are easier to review within 1-2 business days when drawings, graphite grade, quantity, and destination are included.
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Expansion Volume | 150 - 350+ ml/g | Determines the thickness and effectiveness of the insulating char layer formed during a fire. |
| Carbon Content | 85% - 99% | Higher carbon purity provides better thermal stability and fewer impurities in the final product. |
| pH Value | 5.0 - 8.0 | Neutral pH is critical to prevent acidic corrosion of processing machinery and metal contacts in end-use (e.g., EV batteries). |
It is halogen-free, non-toxic, and acts physically by forming a thick, insulating intumescent char layer that cuts off oxygen and heat.
The onset temperature must be higher than your manufacturing process temperature (e.g., extrusion) to prevent premature expansion, but low enough to react quickly in a fire.
Yes, we can provide specific grades for compounding trials based on your particle size and expansion requirements.
