700 Class Thermal Interface
The eGraf™
700 Class of thermally
conductive interface materials is designed
for
use in applications requiring high
thermal
conductivity, low clamping loads
and
low contact resistance.

eGraf 700 Class products are manufactured
entirely from natural graphite with no fillers or binders.
The conformable nature of eGraf 700 Class
products optimizes the thermal conductivity properties at low system loads.
eGraf 700 thermal interface is an excellent replacement
for thermal grease or phase change materials.
No release liner is required. Typical applications include DC to DC
converters, microprocessors, and hot and cold plates.
