Widely used in industries such as power, petroleum, chemicals, instrumentation, machinery, and diamond tools, graphite paper is ideal for both dynamic and static seals, replacing traditional materials like rubber, fluoroplastics, and asbestos¹. Additionally, in the context of electronic products, a new cooling solution has been introduced using natural graphite. This innovative approach utilizes graphite paper for efficient heat dissipation. Graphite paper offers high thermal efficiency, compact size, lightweight properties, and uniform heat conduction in both directions, enhancing the performance of consumer electronic devices.
