In this process, the graphite expands almost 300-350 times of its original volume and takes the shape of worms. These worms can be pressed or rolled into any desired shape without any binder. The exfoliated graphite sheets show excellent electrical properties i.e. high dielectric constant (ε = 6.374 ×107) and comparatively low dielectric loss (tanδ = 138) across the frequency in the range 50 Hz to 30 MHz and temperature in the range 40-300 °C. The products developed from exfoliated graphite can have very good sealing applications in industrial areas, especially for gaskets in the automobile industries. popup.nrat_date 2025-03-24 Close
