Graphite felt is available in several thicknesses and widths to match the specific application. It is most commonly used as an insulating material, such as cladding, heat shields, or filters. Most of the felt is low density to help improve performance by letting a furnace or similar object heat and cool at a quicker rate. This low density also helps to control and stabilize the temperature to create the atmosphere that is more constant and maintains the more productive heat all the way through.
The felt can have an extra coating which is useful to give more protection against erosion. Graphite felt is made to be easy to cut to size and install in place. Plus, there is a rigid form of this material and created in a variety of shapes, such as rings, cylinders and baffles.
Here are a few of the popular uses of graphite:
The use of graphite is common in the ceramics industry to help increase performance while the furnaces are working at high temperatures, as well as giving greater mechanical strength and electrical conductivity.
Graphite is the preferred material to use in place of asbestos in the automotive industry and can feature in a variety of areas, such as the brake lining and gaskets. Plus, it is a major aspect of brushes used in the electric motors.
Graphite is a practical choice for a wide range of military aerospace vehicles because of the ability to endure high temperature ranges. Also, this material is a useful choice for space shuttles and applied as surface tiles. The material is very stable with high resistance properties, and can endure temperatures that reach up to 3000 degrees C.
The use of an ultra-pure form of graphite is becoming more popular in electrical circuitry and components because of the increasing reliance on computers. Also, the graphite is a favored choice for electrical circuits and systems that rely on automation.
In addition to graphite, there is also a carbon fiber felt which is a similar type of material and useful in applications that need high temperature insulation, such as furnaces. This material also has high heat properties even with thin layers to provide the reliable and long-term insulation results. Plus, this material is able to avoid contracting or shrinking to help maintain the consistent heat and avoid issues with hot sports or cavities.
