China carbon fiber felt for crystal growing furnace/solid carbon fiber felt/ regid carbon fiber felt

Carbon fiber composite hard felt and application

The use of foreign high-quality polacrylonitrile-based raw silk, made by carbon felt matting technology into a carbon felt, and use a small amount of binder to produce the desired product shape after curing, and through a 2400 degrees high temperature graphite forming. The hard felt adopts the density gradient structure technology, and performs various surface processing or purification processes to ensure that the material has the best thermal insulation performance and better oxidation resistance at the high temperature stage, helping the customer to reduce energy consumption and reduce costs.

Flat plates are used in high temperature vacuum sintering furnaces and inert gas protection furnaces such as monocrystalline silicon, polycrystalline silicon crystal growth furnaces, quartz furnaces, vacuum furnaces, induction furnaces, high frequency furnaces and heat balance reactors, heat treatment furnaces, carbide production, sintering furnaces , Welding furnaces, high pressure furnaces and other high-temperature furnace insulation materials.


Cylinders are widely used in insulation materials such as monocrystalline silicon, polysilicon, compound semiconductors, optical solders, and other high-temperature crystal growth furnaces.
