Rayon Base Carbon felt/Graphite felt
Hifounder Rayon-based carbon felt/graphite felt is made of viscose rayon as raw material. It is a high-temperature insulation material with excellent performance, such as Light weight, soft, high carbon content, high temperature resistance, non-volatile, and ablation resistance. Therefore mainly used as resistant ablative material and ultra-high-temperature vacuum metallurgical equipment ,insulation materials and other composite materials,can also be used for high-performance body far-infrared heat.
Product Info
Hifounder Rayon-based carbon felt is made of viscose rayon as raw material. It is a high-temperature insulation material with excellent performance, such as Light weight, soft, high carbon content, high temperature resistance, non-volatile, and ablation resistance.
Rayon-based graphite felt is made of viscose fiber as the base material. It is formed after high-temperature treatment of pre-oxidation, carbonization and graphitization.
It has good shape retention, self-supporting properties, small specific gravity, no short fibers falling off, high surface finish, low thermal conductivity, high temperature resistance, good thermal shock resistance (no cracking or deformation for long-term use), long service life and easy to install and replace. The operating temperature can reach 3000°C. It is an ideal new heat insulation material for high-temperature vacuum equipment and high-temperature equipment in non-oxidizing atmosphere.

Application
Hifounder Rayon-based carbon felt mainly used in medium-frequency induction high-temperature sintering furnaces, Industrial production of ablation-resistant materials and strict thermal insulation materials for ultra-high temperature vacuum metallurgical equipment and other composite materials. It is also suitable for use as heating element materials for quartz heating tubes and felts for marking machines.
Hifounder graphite felt is resistant to ablation, has excellent thermal insulation perfprmance, and less slag. It mainly used photovoltaic enterprise furnace types such as monocrystalline silicon furnaces, polycrystalline silicon furnaces, silicon carbide recrystallization furnaces, vacuum high-pressure gas quenching furnaces, etc.
