Conventional Composite Hard Felt is a new type of thermal insulation material compounded by a special process.

Hard Felt Suitable for Vacuum sintering furnace. (Carbide sintering furnace, Quenching furnace, Carburizing furnace, Pressurized gas quenching furnace, Metallurgical powder sintering furnace, Medium frequency induction furnace, Brazing furnace, Ceramic sintering furnace)

Advantages:

No pollution in hot cell, pressure resistance, strong anti-radiation ability, long service life, energy-saving, resistance to airflow impact, good thermal insulation effect, Its life span is 3 times that of soft felt.

Application:

• Heat insulation material for high temperature vacuum furnace
• Used as a reinforcement material to produce carbon / carbon composite materials

Characteristic:

Polyacrylonitrile-based carbon felt is a kind of 3-16mm thick felt made of polyacrylonitrile-based original felt after thermal stabilization and carbonization treatment. Since 90% of carbon felt is pores, it has excellent thermal insulation performance in vacuum or inert atmosphere,especially under high-temperature conditions, it has the characteristics of light weight, small specific heat capacity, soft texture, good thermal insulation, easy operation, etc. It has stable performance and is especially suitable for intermittent operation of high-temperature vacuum furnace, which can save a lot of energy.

Physical and chemical indicators:

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.
