Polyacrylonitrile(PAN) Based Carbon felt or Graphite felt
Polyacrylonitrile based carbon fiber felt is light in the quality, small in specific heat capacity, soft in texture, good in adiathermancy and convenient in operation, which can save great nergy. Therefore, thermal insulaion of the polyacrylonitrile base is extremely superior in vacuum or inert atmosphere, in particular, performance of the polyacrylonitrile base is stable under high temperature condition, and it is the execllent thermal insulation material for Vacuum Furnace.
Hifounder Polyacrylonitrile based graphite fiber felt is formed by subjecting the high quality polyacrylonitrile base carbon fiber felt to pyrographite treatment. It is light in quality, good in flexibility, high in carbon content, high temperature resistant, without volatilization under high temperature, corrosion resistant and small in heat conductivity coefficient and high in shape retention. It is fine heat insulation for polysilicon and monocrystalline silicon.
