1mm Thickness Expanded Soft Graphite Foil

  Product Description   Description of 1mm Thickness Expanded Soft Graphite Foil
  1mm thickness expanded soft graphite foil can work at -250-700  ℃ air condition, -200-3000 ℃  vacuum or inert environment. our foil has a powder well price, you should be satisfy with it. It can be wrapping, this foil is popular in heat industry.    The Producing Process of 1mm Thickness Expanded Soft Graphite Foil  .   1. A brief introduction of the whole production line.  We use this production line to produce the flexible graphite foil.  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-expandable graphite    The expandable graphite comes from good mine and mineral resources,  making sure the superior quality of the expandable graphite  and a good start of the production from the beginning.   3. The mixing process.    In this process, the expandable 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 expandable 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 expandable 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 foil.    After passing through the material pool, the flexible graphite sheet is preliminary for med.   7. The adjusting process of the density and thickness of the flexible graphite foil.    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 foil is produced.   Technical Specifications:
