Size Specifications: Customizable dimensions based on client drawings or requirements, including diameter, thickness, and length—suitable for a wide range of industrial applications.
Purity Level: Available in various purity grades from 80% to 99.99%, tailored to meet performance needs such as high temperature resistance, conductivity, and lubrication.
Particle Size (Granularity): Graphite powder can be customized with particle sizes ranging from a few microns to several hundred microns, ideal for lubricants, conductive materials, and additives.
Expansion Ratio (for expandable graphite): Adjustable expansion ratios such as 100–300 times, depending on application requirements—commonly used in flame retardants, gaskets, and sealing materials.
Introduction
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.
Soft Graphite Felt Features
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.
