PAN Based Graphite Insulation Felt Erosion Resistance Board for Crystal Growing


Our Chemshine graphite thermal insulation board can be used in single crystal furnace for crystall grwoing.

The board is made out of rigid carbon fiber. It is PAN based and also can be based on carbon fiber cloth, carbon felt or graphite felt material bonded by a special process,it has certain shape retention,self supporting, the proportion of samll ,no staple fiber loss,low coefficient of thermal conductivity,thermal shock resistance,erosion resistance,long service life,easy installation dismantled,

Our PAN based graphite insulation felt board is mainly used as insulation in high-vacuum and inert atmosphere furnaces. This kind of high-vacuum is widely used for metal heat treatment, meticulous and ceramic sintering, different kinds of crystallization production, producing optical fiber, and sintering monocrystalline silicon for semiconductors, usually in a high-vacuum or inert atmosphere furnace. We pride ourselves in the ability to offer first class technical backup to our customer base, and over the years. We have developed close technical partnerships with major fields including Aerospace, Semiconductor, Automotive, Specialist Castings, Metal Composites, Crystal Growing, Hard Metal Sintering, Graphitizing, and the Heat Treat Sectors.

  • Metalizing (metal heat treating): Heat treating furnaces, sintering, brazing furnaces.
  • Fibers manufacturing: Carbonizing furnaces, graphitizing furnaces - induction or resistance tube furnaces.
  • Float glass industry: Insulating fasteners (part of liners).
  • Tool manufacturing: Sintering and hot pressing.
  • Universities and Government Research Centers: High temperature furnaces, fuel cells.
  • Aerospace: Hot isostatic process furnaces, heat treating, sintering, brazing furnaces, autoclaves.
  • Semi conductors: Silicon pullers, gallium arsenate producers, furnaces.
