Graphite hard felt also has a certain degree of rigidity, self-supporting, small specific gravity, no staple fiber shedding, etc., and long service life, easy to install and remove.
According to the need, graphite hard felt can be cut, folded or sewn, processed into various shapes and sizes to meet different application requirements.
Graphite hard felt is highly resistant to corrosion, not easy to chemical reaction with other substances, has good chemical stability.
At high temperatures, graphite hardfelt maintains its physical and chemical stability and can withstand high-temperature environments up to 2000°C, making it an ideal choice for high-temperature working conditions.
Graphite hard felt can effectively reduce heat loss and maintain high temperature environment, thanks to its low thermal conductivity, which can prevent heat conduction and improve the thermal insulation effect.

Vacuum and inert gas furnaces (thermal insulation); Semiconductor manufacturing (wafer processing, CVD reactors); Aerospace applications (thermal protection); Energy storage (fuel cells, batteries); Metallurgy (heat shields, insulation in sintering processes).
It is typically cut to fit the required shape and assembled in layers or panels within furnace chambers. Adhesives, mechanical fasteners, or ceramic spacers may be used for securing the material.
Graphite begins to oxidize at temperatures above ~450°C in an air environment. For high-temperature applications, protective coatings or an inert gas atmosphere are recommended.
Yes, it can be machined into different shapes and thicknesses to fit specific industrial applications. Coatings can also be applied to enhance oxidation resistance.
Graphite hard felt is produced by carbonizing and graphitizing soft felt under high temperatures, often with the addition of a resin binder to create a rigid structure.
Graphite hard felt is a rigid, high-purity insulation material made from carbon or graphite fibers bonded together with a carbonized resin. It is used primarily in high-temperature applications, such as vacuum furnaces and thermal insulation for industrial processes.
