Graphite Sheets

TGON 800

Tgon 800 Series

High-Performance, Cost Effective Thermal Interface Material

Used where electrical isolation is not required, Tgon™ 800 is ideal for where electrical contact and thermal transfer are desired.

Its unique grain-oriented, plate-like structure provides a high thermal conductivity of 240 W/mK in the XY plane and 5 W/mK through the z-axis. Tgon 800 can be supplied in 12” x 18” (305mm x 457mm) or 18” x 24” (457mm x 610mm) sheets, rolls or die-cut to specific configurations.

It is also available with proprietary pressure sensitive adhesive on one side. This adhesive coating is the thinnest available, minimizing any impact on thermal performance.

• High thermal conductivity of 5 W/mK in Z axis and 240 W/mK in the X-Y axis

• >98% graphite

• Low thermal resistance

• Thicknesses of 0.005”, 0.010” and 0.020” (0.125mm, 0.25mm, and 0.50mm)
