Graphite Accessories of Vacuum Furnace

Product Description:

The Graphite Felt is normally classified into asphaltic based Graphite Felt, PAN based Graphite Felt & rayon-based Graphite Felt. The main 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.
