Graphite Felt
Product introduction:
The graphite felt is normally classified into asphaltic based graphite felt, PAN based graphite felt and rayon-based graphite felt. The mainly application is electric conduction in the photovoltaic industry, as the heat retaining material, thermal insulation material for the smelting furnace and vacuum furnace, and in chemical industry it could be the filtration material.

There are various selections of the materials. Based on the working environment, our engineers will offer the suitable graphite material.
Do you know making method of the graphite crucible?
The graphite felt is formed after above 2000°C high temperature treatment under inert gas or vacuum.
The polypropylene cyano is the major raw material. The polypropylene cyano carbon felt or rayon-based carbon felt is cut into the specific dimension, and loaded into the graphite vessel after rolled.
The graphite vessel will be setted in the high temperature furnace, protected in vacuum or by high pure inert gas. It's heated up to 2200-2500°C with the heating rate 100-300°C/h, then get the final product after naturally cooled to 100°C.
