Panasonic's EYG-S121807DP pyrolytic graphite sheet is a high-performance thermal interface material designed for efficient heat dissipation in various electronic applications. Constructed from a highly oriented graphite polymer film, it boasts exceptional thermal conductivity (700 to 1950 W/(m-k)), lightweight properties, and flexibility, allowing for easy customization and integration. The SSM (Semi-Sealing Material) variant further enhances performance by combining the graphite sheet with a thermally conductive elastomer resin, improving adhesion and reducing stress on electronic boards. Common applications include smartphones, tablets, LED devices, and semiconductor manufacturing equipment.
