Graphite Felt Cylinder

Graphite Felt Cylinder


MTE select excellent PAN flat felt as basic material, produce carbon fiber felt and graphite fiber felt through preliminary heat treatment in oxidizing, carbonization, and high temperature purification.

Our felts could be used as thermal insulation material in all kinds of high temperature vacuum furnace, also could be used as reinforcement material for carbon carbon composite.


-High temperature resistance

-Corrosion resisting

-High purity, low ash content

-Good resistance to air scour

-Long service life

-Easy to cut and assemble

-Easy to shape
