Flexible Graphite ---Carbon and Graphite Felt

Flexible carbon and graphite felt is an insulating material manufactured by carbonization of natural and synthetic fibers with unique textile, chemical and thermal properties. Rigid graphite felt is a shape-retentive insulating material made from graphite fibers or felt and a carbon binder.

Typical Applications
· Furnace – resistance or induction heated vacuum furnaces and inert gas furnaces, such as
　 degassing furnaces, brazing furnaces, soft and bright annealing furnaces, sintering furnaces for
　 hard metals, carburizing furnaces, laboratory graphitizing furnaces; inductively heated melting and
　 heat treatment furnaces, in which a proportion of the ceramic insulting material is replaced by felt
　 in order to increase the electrical efficiency and prevent the liquid metal from coming into contact
　 with the induction coil in the event of crucible fracture (no wetting)
· Nuclear reactor technology (small cross-sectional area for neutron absorption)
· Thermal insulation, as filters, and as catalyst support
· Porous electrodes
· Turbine blade manufacturing
