              Factory price expanded thermal graphite plate




Graphitesheet  is a kind of totally new thermal & radiating material, heat conducting evenly along two directions, shielding with heat and component while improving the performance of the consumer electronic products


Typical application: 


-between the Circuit board chip and heat sink of LCD-TV

-PDP chip and IC

-between the transformer and the shell.

-between Led particle base and aluminum plate

-between PCB board and its shell

-between IC and heat sink

-laptop NB display card and network card

-between STB C and heat sink or shell



1.The manufacturing process of the flexible graphite sheet:




1> A brief introduction of the whole production line.


We use this production line(as the following photos present) to produce the flexible graphite sheet. This production line adopts international advanced technologies, making us produce high quality flexible graphite sheet and having become a powerful tool for us to meet the different requirements of our customers.


2> The raw material-expansible graphite.


The expansible graphite comes from good mine and mineral resources, making sure the superior quality of the expansible graphite and a good start of the production from the beginning.


3> The mixing process.


In this process, the expansible graphite is poured into the mixer to be well mixed. And after the mixing, they go into the hopper.


4> The expansion process.


After mixing, the expansible graphite goes into the expansion stove to be high temperature expanded. The S,chlorine and many other chemical elements are get rid of from the expansible graphite in the expansion stove


5> The transportation of the having been expanded graphite.


In this process, the graphite is transported by the draught fan from the expansion stove to the material pool.



6> The preliminary roll-forming of the flexible graphite sheet.


After passing through the material pool, the flexible graphite sheet is preliminary formed.



7> The adjusting process of the density and thickness of the flexible graphite sheet.


There are many groups of rolls in the production line. Through these rolls, the adjusting of the density and thickness is fulfilled.



Then the flexible graphite sheet is produced.
