NGS
The Natural Graphite Sheet NGS is a thermal management material featuring a unique layered structure and crystal orientation that provides excellent in-plane thermal conductivity ranging from 300 to 500 W/m·K. This natural graphite sheet offers low through-plane thermal conductivity of 5-20 W/m·K, creating an efficient thermal diffusion solution for electronic cooling applications. With a thickness of 0.03mm and specific gravity between 0.9-2.0 g/cm³, this thermal conductivity material maintains high volume resistivity of 3.0×10¹³ Ω·cm, ensuring electrical isolation while effectively managing heat.

This natural graphite sheet demonstrates reliable performance across a wide temperature range from -40°C to +500°C, making it suitable for demanding electronic environments. The material features a tensile strength of 715 PSI (4900 kPa) and Shore C hardness of 80, providing mechanical durability for various applications. With UL94 V-0 flame rating and RoHS compliance, this thermal management solution meets international safety and environmental standards.

Applications include laptop computers, smartphones, communication devices, digital cameras, and tablet PCs where efficient heat spreading is critical. The natural graphite sheet can be custom die-cut into various shapes with edge wrapping protection to prevent graphite shedding and potential circuit issues. Its black color and flexible nature allow for seamless integration into compact electronic assemblies.

The material's high thermal conductivity in the horizontal direction enables effective heat dissipation from hot spots to larger areas, improving overall thermal performance. The natural graphite sheet's low thermal resistance ensures minimal temperature gradients across surfaces, enhancing device reliability and longevity. This thermal management solution represents a balance of performance, safety, and adaptability for modern electronic cooling requirements.
