Reinforced Composite Hard Felt - Shaped Pieces

The Hunan MTR hard composite graphite felt is made of PAN (polyacrylonitrile) carbon fiber graphite felt through curing, carbonization and high temperature purification processing.

• Core material: polyacrylonitrile
• Form: Microporous
• Material thickness: 5-300mm
• Operating temperature in air: < 350 ℃
• Working temperature in vacuum: < 2200 ℃
• Operating temperature in atmosphere: < 3000 ℃
• Carbon content: above 98%
• Density: 0.18-0.32g.cm3

Physical and chemical indicators:

Temperature resistance: 2200 ℃ in vacuum, 3000 ℃ in inert gas

The density of this product is 0.18-0.35g/cm3. The surface can be coated with graphite paper or carbon cloth, carbon cloth and graphite paper, graphite paper can be sandwiched between each felt. It can prevent surface fluff, gas leakage (convection), and protect its surface (prevent loss) and increase the strength of hard felt.

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.
