Why should I use eGraf Thermal Interface for my electronic thermal applications?

eGraf Products are a unique thermal interface material in that they are manufactured entirely from nature graphite with no fillers or binders. This distinctive form of graphite benefits you in the follow manner:

· eGraf Thermal interface products are highly conductive. The 700 Class of materials have a thermal conductivity of 7 W/mK and the 1200 Class have a thermal conductivity of 12 W/mK. Combined with contact resistance values as low as 0.03 °C in2/W, the overall thermal resistance of eGraf products is less than other tapes, pads or gap fillers. eGraf materials take up less of your thermal budget, and reduce power constraints that can increase system complexity and cost.

· eGraf Thermal Interface materials are available in thicknesses up to 1.5mm (0.06"), and are able to accommodate mismatched surfaces and large gaps that are beyond the reach of thermal greases or phase change materials.

· eGraf is thermally stable. Standard eGraf grades will not dry out, become brittle or degrade in performance over time due to temperature or humidity excursions. The coefficient of thermal expansion (cte) for both 700 and 1200 classes of interface in the through sheet (z direction) is 27 x 10-6 m/m °C and in plane (x-y direction) is -0.4 x 10-6 m/m °C.

· All eGraf grades are compressible and conformable at low loads. These characteristics allow for low specific thermal resistance.

· The crystalline structure of eGraf natural graphite products leads to unique directional differences in the thermal performance. 700 Class Products conduct at 7 W/mK through the sheet and approximately 200 W/mK in plane. 1200 Class products conduct at 12 W/mK through sheet and approximately 200 W/mK in plane. This directional behavior spreads heat, dampens hot spots and helps maximize the performance of a heat sink by using more heat sink surface area.

· eGraf Thermal Interface Classes 700 and 1200 are non flammable. 700 and 1200 Class materials are recommended in temperature ranges which far exceed other commercially available products. Standard eGraf 700 and 1200 Class Interface Products can be used in oxidizing environments at temperatures which range from -240 to 450°C.
