Graphite Interface Materials
thermal management interface materials from
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 Thermal Interface Ordering Information

7WW-X
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.
