Audited Supplier Carbon felt,Graphite felt
In the vacuum condition or inert environment, the heat-insulating property of graphite felt is superior, especially in the high temperature condition. Light weight, small specific heat capacity, softness, and superior heat-insulating property make the graphite felt applicable to discontinuous running vacuum high temperature furnace. It can save a lot of energy, it's the fine heat-insulating material for vacuum metallurgy equipments.
Polyacrylonitrile-based graphite felt is made of high quality carbon felt by high temperature processing. It has the advantages of light weight, high purity, good thermostability, anticorrosion, small thermal conductivity, and good shape retention, it's good heat insulating material for monocrystalline silicon furnace and polysilicon furnace, and also good anticorrosion filter materials.
