Graphite felt is divided into three types: asphalt-based graphite felt, polyacrylonitrile-based graphite felt and viscose-based graphite felt, depending on the type of raw felt used. It is mainly used as thermal insulation material for single crystal silicon smelting furnaces. In the chemical industry, it can be used as a filter material for high-purity corrosive chemical reagents. Carbon felt is treated at a high temperature of more than 2000°C under vacuum or inert atmosphere to become Awei graphite felt. The product density is about 0.11-0.15g/cm3, with good thermal insulation performance, and can be cut into the required size for production. The carbon content of our company's graphite felt is higher than the carbonization temperature of the general market, so the purity is improved and the service life is also extended.
