Graphite Felt

We supply many types of graphite soft felt, by different fibers and production techniques, into PAN-based, ,RAYON-based and Soft felt for battery. 


It is formed by polyacrylonitrile based carbon felt processed in graphitization treatment. It has very small density, high content of carbon, and resists high-temperature without volatilization, good corrosion resistance, small thermal conductivity, good memory of shape maintenance.

It is good for high-temperature vacuum furnace, especially for the material of solar silicon, sapphire and semiconductor. It can also be used as quality filter material under high-corrosion condition.
