1200 Class Thermal Interface  

 

 

 

The eGraf™ 1200 Class of thermally

conductive interface materials is designed

for use in applications requiring high

thermal conductivity, low clamping loads

and low contact resistance. 

 
 
 

 

 

 

 

 

 

 

 

 

 

 

 

 

 


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.
