Soft Felt - Graphite Felt

• Performance And Application Of Graphite Felt

Polyacrylonitrile-based graphite felt is stronger and more resistant to oxidation than viscose-based graphite felt, but it has poor flexibility, large bulk density, and good thermal insulation performance. In addition to their high purity, high-temperature resistance, corrosion resistance, and non-melting characteristics, they also have the advantages of elasticity, foldability, tailoring, and sewing with graphite yarn. The main use of graphite felt is as a thermal insulation material for single crystal silicon smelting furnace. In the chemical industry, it can be used as a filter material for high purity corrosive chemical reagents. Under a non-oxidizing atmosphere, the temperature of the graphite felt can reach 3000 ℃.

• Definition Of Graphite Felt

• Carbon felt becomes graphite felt after being treated under high temperature above 2000 ℃ under vacuum or inert atmosphere, its carbon content is higher than carbon felt, up to 99%. At the end of the 1960s, there was already a supply of graphite felt in the world. Graphite felts are classified into three types: pitch-based, polyacrylonitrile-based graphite felts and viscose-based graphite felt due to the different raw felts.

Hunan MTR New Material Technology Co., Ltd. (formerly Zhuzhou Green Carbon Fiber Products Co., Ltd.) is a high-temperature furnace thermal insulation material production plant! Our company adheres to the corporate philosophy of singularity, focus and professionalism, and is committed to the continuous development and application of thermal insulation material technology.

The company’s main products include graphite hard felt, reinforced composite hard felt, multi-type composite hard felt (made in an overall shape), graphite felt, high-temperature carbon felt, and other thermal field insulation materials. The rigid felt series have a rigidity that traditional insulation materials do not have. Supporting, high strength, no short fiber shedding, low thermal conductivity and other advantages, more energy-saving, environmentally friendly, easy to disassemble, easy to maintain, and can extend the service life of the high-temperature furnace. The product is suitable for all kinds of high-temperature vacuum furnace equipment (such as: single crystal growth furnace, polycrystalline casting furnace, polycrystalline reduction furnace, polycrystalline ingot furnace, vacuum sintering furnace, hot pressing furnace, heat balance furnace, electromagnetic induction furnace, medium and high-frequency Induction furnaces, non-oxidizing atmosphere high-temperature equipment, high-purity silicon hydrogenation furnaces, etc.) are widely used in solar energy, vacuum metallurgy, new chemical materials, atomic energy, semiconductors, new electronic energy and other fields.

Customized drawings can be made to produce various non-standard and special-shaped geometric shapes such as flat plates, discs, cones (discs), and cylinders! Can provide the overall installation service of the hot cell.
