We supply two kinds of soft carbon and graphite felt , it’s material is PAN fiber and RAYON fiber.PAN fiber material widely applied to verity vacuum resistance

furnace、induction furnace、Sintering furnace.It is　excellent in thermal insulation．RAYON fiber is execellent in high- temperature thermal insulation . It is like as

other Carbon felt and it is density smaller、thermal conductivity smaller, it is better in thermal insulation and ablation.

Soft carbon fiber felt
Main applications: it is used as thermal insulation material; as reinforced material to produce carbon-carbon composite material.
Characteristics: pan carbon fiber felt flatbed are produced from pan felt by stabilization and carbonization. Because 90% are space in the felt, so the effect of

thermal insulation function is very good under vacuum or inert gas. It has a stable function under high-temperature. Because it has very small density, small specific

heat volume, soft nature, good thermal insulation function, easy operation, it is very fitful for high-temperature vacuum furnace under intermittent operation. It can

save energy sources as flatbed felt, it can be compounded with carbon into carbon-carbon composite material.

rigid:  Hard composite carbon fiber felt

The material is formed by inteerating graphite paper, carbon felt and carbon cloth, and then qubjecping then to secondary high temperature purification treatment. The

material is superior in ablation resistance performance, thermal shock resistance performance, airflow washing proof performance and thermal insulation performance. It

is mainly used for vacuum high pressure air quenching furnace, low pressure fritting furnace, pressurization vacuum sintering furnace etc.
