Soft Graphite Felt

Soft graphite felt is a flexible insulating material for high temperature applications in inert or vacuum environments and is entirely made of carbon fibers. When used as an insulation material for high-temperature industrial furnaces, it can be bound and stitched with carbon ropes woven through special process. Due to its controlled internal structure and electrical conductivity, soft felts can also be used for energy storage like redox flow cells. Soft graphite felts are divided into PAN-based soft graphite felts, rayon based soft graphite felts, and soft felts for battery.

1、Low thermal conductivity and static-free

2、Low specific heat

Allow for rapid heating and cooling of furnaces.

3、High temperature stability

In oxidizing environments up to 350 °C, in protective or vacuum environments up to about 3000 °C for graphite and 1000 °C for carbon.

4、Easy machining

Can be cut with scissors or blades and suitable for small bending radius.

5、Good surface properties

Not subject to all molten metals.

6、High purity

Low sulfur and ash contents.

7、High resistivity

Coupling in an inductive field only occurs above 12 kHz.
