Brief

High-quality polyacrylonitrile-based carbon made of the pan (polyacrylonitrile) graphite felt after high-temperature graphitization treatment.

It has the characteristics of lightweight, good flexibility, high carbon content, low thermal conductivity, high-temperature resistance, corrosion resistance, and stable shape.

CHARACTERITICS

Graphite felt is usually divided into asphalt cornerstone ink felt, pan graphite felt and graphite felt viscose base. It is mainly used in the conductive photovoltaic industry as thermal insulation material for smelting furnaces and vacuum furnaces. It can filter materials in the chemical industry.

  • This is a superior thermal insulation material for polysilicon and monocrystalline silicon furnaces, and can also be used as corrosion-resistant filter material.

  • PAN-based soft graphite felt is an effective insulating material. The effective application temperature in inert gas or vacuum insulating materials is up to 2000 ° C.

  • Reinforcing structure for C/C composite components and other products..

  • The marking machine used felt.

APPLICATION

  • Heat insulation materials.

  • Boiler thermal insulation materials.

  • Vacuum furnace heat insulation felt.

  • Carbonization furnace thermal insulation felt.

  • Graphitization furnace thermal insulation felt.

  • Single-crystal silicon polysilicon pull crystal furnace heat insulation felt.

  • High-frequency Induction high-temperature sintering furnace thermal insulation materials.

ADVANTAGE

  • Due to its high purity, it is the most used carbon felt. For a wide range of cell and fuel cell applications, they have less chemical reactivity and higher conductivity (thermal and electrical).

  • PAN-based graphite is used as the electrode pad of various battery designs, including all vanadium redox flow batteries, Including vanadium redox flow batteries.

  • It supports advanced battery manufacturers’ need for highly uniform carbon felt to ensure the reliability and durability of electrochemical systems.

  • Its high conductivity, high purity, chemical resistance, and carb battery felt make them ideal for liquid flow battery developer design standards.

ADVANTAGE

  • When used as a holding furnace for smelting furnace and vacuum furnace, the flexibility of PAN-based carbon felt allows the formation of a thermal insulation layer around the furnace wall.

  • Generally, it is used as a protective barrier between the furnace wall and the rigid insulation to eliminate any irregularities and compensate for the expansion difference between two different materials.

  • It enables the battery to have high coulomb efficiency, energy efficiency, and voltage efficiency at 1.00-ohm-cm ² It has very low impedance.

  • It has longer long-term stability (physical stability and superior performance stability) than other materials.

  • Suitable for high-temperature vacuum furnaces, especially solar silicon, sapphire, and semiconductor materials. It can also be used as high-quality filter material under high corrosion conditions.
