Product Core
Rolled Graphite is a high-performance flexible graphite made from high-purity natural flake graphite through chemical expansion, high-temperature treatment and precision rolling. It retains graphite's superior thermal conductivity, electrical conductivity and chemical stability, while offering excellent plasticity and processability to form high-density, uniform sheets. A multifunctional material combining sealing, thermal conduction, electrical conduction and high-temperature resistance, it addresses limitations of traditional materials in harsh environments-including poor flexibility, weak corrosion resistance and narrow temperature range-and is widely used in industrial sealing and thermal management systems.
