Rayon Graphite Felt

RAYON graphite fiber felt is an inorganic fiber product made of graphite as raw material. It has high temperature oxidation resistance and good thermal conductivity. It is woven from man-made fibers. Cut the woven fabric into customized sizes (generally 1M, 1.2M, 1.5M width), put the entire roll of woven fabric into a graphite container, and place the graphite container at high temperature. In the furnace (graphite tube furnace, medium frequency, high frequency induction furnace or other high-temperature furnace with heating form), evacuate the high-temperature furnace or add high-purity inert gas for protection, and heat the high-temperature furnace at a heating rate of 100 to 300°C per hour. to 2200~2500℃, and then naturally cool the high-temperature furnace to 100℃. The graphite felt products produced are extremely rayon graphite felts.

Characteristics

 

It is mainly used for thermal insulation, heat insulation and refractory materials in high temperature environments. Graphite fiber felt has the following characteristics:
(1) Good high temperat
ure resistance: Graphite fiber felt can maintain good stability and heat resistance at temperatures up to 2500°C.
(2) High strength: Graphite fiber felt has high tensile strength and compressive strength and can withstand certain mechanical pressure.
(3) Excellent thermal conductivity: Graphite fiber felt has good thermal conductivity and can effectively reduce the transmission loss of heat energy.
(4) Good thermal insulation performance: Graphite fiber felt has good thermal insulation performance and can effectively isolate heat conduction between high temperature environment and low temperature environment.
(5) Good chemical stability: Graphite fiber felt has good stability to most chemical substances and is not susceptible to corrosion

Difference from Pan Graphite Felt

 

Rayon graphite felt and pan graphite felt are two high-temperature, heat-insulating and flame-retardant graphite fiber materials commonly used in industry. Although they may look similar, they have some significant differences.
First of all, Rayon graphite felt is woven from rayon fibers. This process creates a soft, stretchy material that is highly resistant to heat and chemicals. .
Secondly, the thermal conductivity of Rayon graphite felt is generally lower than PAN graphite felt. This means that the rayon variant can provide better insulation, making it suitable for use in applications that require thermal insulation.

Overall, both rayon graphite felt and pan graphite felt have their own unique advantages and disadvantages and should be selected based on the specific needs of the application. It is crucial to consult with a professional to ensure you choose the right materials for your project.
