Hard carbon fiber felt

Viscose-based carbon fiber
carbon fiber composite felt
Rigid composite graphite felt
Availability:
Quantity:

Viscose-based carbon fiber composite felt is made of viscose-based carbon fiber composite curing molding and secondary high-temperature purification treatment. It has anti-ablation performance, thermal shock resistance, air erosion resistance and heat insulation performance, heat preservation performance and longer service life.


carbon fiber composite felt is made of T300 carbon fiber overall composite curing and shaping, followed by secondary high-temperature purification treatment. Ablation resistance, thermal shock resistance, air flow erosion resistance, heat insulation performance, heat preservation performance and service life are all excellent. It is a high-end material suitable for vacuum industrial furnace equipment in the electronics and semiconductor industries.

Rigid composite graphite felt adopts a special process to combine graphite paper, polyacrylonitrile-based graphite felt, and polyacrylonitrile-based carbon cloth into one, solidify and shape, and make it through secondary high-temperature purification treatment. It has high purity, high carbon content, and is resistant to burning. Corrosion performance, thermal shock resistance, air flow erosion resistance and thermal insulation performance, excellent thermal insulation performance, mainly suitable for ultra-high temperature vacuum high pressure sintering furnaces and electronics, semiconductor industries, solar photovoltaic (polycrystalline casting furnaces, single crystal furnaces), vacuum industrial furnaces equipment.
