PAN-based Graphite Felt

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 resistant 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.
