Anti Corrosion Polyacrylonitrile Carbon Graphite Felt Light Weight

Graphite Felt

• Polyacrylonitrile based graphite felt

Polyacrylonitrile-based graphite felt is obtained by special high-temperature graphitization treatment of acrylonitrile-based carbon felt. It has light weight, good interference,
High purity, high carbon content, high temperature resistance, corrosion resistance, low thermal conductivity, and a high degree of shape retention. It is suitable for polycrystalline silicon, single crystal silicon, and single crystal silicon preparation furnaces. Excellent thermal insulation material is also anti-corrosion filter material.
Polyacrylonitrile-based carbon felt has 90% voids in the carbon felt, so it has excellent thermal insulation performance in vacuum or inert atmosphere.
Especially stable performance under high temperature conditions. Because of its light weight, small specific heat capacity, soft texture, good thermal insulation, and convenient operation,
It is especially suitable for high-temperature vacuum furnaces with intermittent operation, which can save a lot of energy. It is an excellent thermal insulation material for vacuum metallurgical industrial furnace equipment.

• Hard composite graphite felt
  Graphite paper, polyacrylonitrile-based graphite felt, solidified and shaped, and two high temperature treatments are prepared by a special process. It has high purity, high carbon content, ablation resistance, thermal shock resistance, airflow resistance, heat insulation, and heat preservation performance All of them are superior, mainly suitable for ultra-high temperature and high pressure sintering furnaces, electronics, semiconductor industries, solar photovoltaic (polycrystalline furnace, single crystal furnace), vacuum industrial furnace equipment.

• Viscose-based graphite felt
  It has light texture, softness, high carbon content, high temperature resistance, no volatilization, and excellent ablation resistance. Therefore, it is mainly used as ablation-resistant materials in the aerospace industry and thermal insulation materials and other composite materials for ultra-high temperature vacuum metallurgical equipment. It can also be used for Xingneng far-infrared heating element.
