eGraf Thermal Interface Ordering Information
12WW-X
eGraf 1200 Class products are manufactured entirely from natural graphite
with no fillers or binders.
The conformable nature of eGraf 1200 Class products optimizes the thermal
conductivity properties at low system loads.
eGraf 1200 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.
