Expandable Graphite

CarboFlameX®

Expandable Graphite for Next-Gen Fire Safety

Halogen-Free • Sustainable • Proven Performance

What is CarboFlameX®?

Advanced Fire Protection Solution

CarboFlameX® is PranaGraf's proprietary halogen free expandable graphite composites engineered to deliver world-class fire protection in various systems and fire standards with zero compromise on sustainability. It is manufactured in India offering a 100% ex-China supply chain.

When exposed to heat, it expands into a protective char layer — slowing fire spread, reducing smoke, reducing melt dripping and shielding base materials. Additionally CarboflameX products offer processing advantages compared to other sources, ensuring compatibility in your product and process.

Fire Retardant Performance

CarboFlameX® is used across various polymers and intumescent systems for superior fire retardancy and prevention.

Engineered to meet the most stringent global fire safety standards, CarboFlameX® delivers reliable intumescent protection, significantly reducing smoke generation and eliminating melt dripping. Its unique expansion characteristics create an insulating char barrier that protects underlying materials and limits fire propagation.
