Specifications
High termperature resistanceStable shape and easy to cut
PAN-based Carbon Felt ( JX-PCF)
PAN(Polyacrylonitrile)-based carbon felt is light in weight, small in specific heat, soft in texture, easy in operation, excellent in heat insulation, and 90% in the carbon felt is interstice, so it’s extremely superior used in the vacuum and inert atmosphere, especially in intermittent vacuum furnace as the excellent heat insulation material to save great energy.
PAN-based Graphite Felt (JX-PGF)
PAN(Polyacrylonitrile)-based graphite felt is made of the high quality PAN-based carbon felt by the process of high temperature graphitization treatment. It has the characteristics of light weight, good flexibility, high carbon content, low thermal conductivity, high temperature resistance, corrosion resistance and the stable shape. It is the superior heat insulation material in polysilicon and monocrystal silicon furnace, and it can also be used as the corrosion resisting filtering material.
