The type segmentation of the Graphite Sealing Material market distinguishes five principal categories: expanded graphite, graphite foil, graphite gasket, graphite composite, and graphite paste. Expanded graphite offers high compressibility and thermal conductivity, making it dominant in high‑temperature sealing, and accounts for roughly 35% of total market revenue. Graphite foil provides superior chemical resistance and is preferred in corrosive environments, contributing about 22% of sales. Graphite gaskets are engineered for precision‑engineered fittings, especially in automotive and aerospace, representing 18% of the market. Graphite composites, which blend graphite with polymer matrices, deliver enhanced mechanical strength and capture 15% of the market share, driven by industrial machinery applications. Finally, graphite paste serves niche sealing needs in micro‑electronics and specialty equipment, adding the remaining 10%. Together, these sub‑types shape the overall market size, and the detailed breakdown is essential for accurate Graphite Sealing Material segmentation analysis.
