Rigid Graphite Felt is shaped insulating materials made by graphitization after forming graphite felt into the customers’ requested shape, such as plate, cylinder, etc. With our special technologies under the high temperature, the density is less than 0.18g/cc, and the carbon content is more than 99.9%. So they are suitable in all types of heat treating furnaces in an inert or vacuum environment.
Applications
– Vacuum furnace insulation
– Inert gas furnace insulation
– Polysilicon, Monocrystalline silicon furnace insulation
Characteristics
– Low thermal conductivity
– High purity
– High-temperature stability
– Erosion resistance
– Easy machinability
