SIGRAFLEX® Graphite Foils with Oxidation Protection

SIGRAFLEX graphite foil with oxidation protection

SIGRAFLEX foils made of expanded natural graphite are distinguished by their high-temperature resistance. They are the first choice in sealing applications for long-term use at high-temperatures due to their extremely low weight loss.

Compared to other industrial graphite foils, our SIGRAFLEX foils with oxidation protection exhibit remarkable oxidation resistance. Their typical weight loss (in TGA test in air at 670 °C (1238 °F) for four hours) is at 2% per hour and less, while conventional industry foils lose up to 40%.
