Western Sahara Graphite Felt

Soft felts and Rigid felts are used in high temperature furnaces, and their main function is to keep warm 3000°C. Due to the low density of the material, the mass of the thermal insulation layer is also light. The thickness ranges from 1.5 to 15mm and the resistance is also higher, which ensures the best thermal insulation design for various systems. In addition, we can also produce soft and rigid felts in custom sizes according to your specific requirements.

Soft graphite felt Applications include

Aerospace: Hot isostatic process furnaces, heat treating, sintering, brazing fur naces, autoclaves. Semi conductors: Silicon pullers, gallium arsenate producers, furnaces.
Metalizing (metal heat treating): Heat treating furnaces, sintering, brazing furnaces.
Fibers manufacturing: Carbonizing furnaces, graphitizing furnaces - induction or resistance tube
furnaces.
Ceramics: Pyro lytic depositing furnaces, CVD furnaces
Quartz/Fused Silica manufacturing: Melting/Sintering furnaces.
Float glass industry: Insulating fasteners (part of liners).
Tool manufacturing: Sintering and hot pressing.
OEM - Furnace manufacturing: Hig h temperature furnaces.
Universities and Government Research Centers: High temperature furnaces, fuel cells.
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、ther mal conductivity smaller, it is better in thermal insulation and ablation.
Notice: when temperature is above 400°C, the product must be used in protective atmosphere or inert gas, It must be kept from moisture> press, when it is transported and stored, It can be cut free geometrical shape.
Pan graphitized felt is from pan carbon felt by graphitization under high-temperature It has very small density, high content of carbon, resists high-temperature without volatilization, good corrosio n resistance, small thermal conductivity, good memory o f shape maintenance It is fitfiil for hig h-temperature vacuu m resistivity furnace, specially for the material of semiconductor It is also for filter material under high-corrosion.

★ Rayon based graphite felt After curing stereotypes and the second high-temperature processing by purification ,It's manufactured by viscose-based carbon fiber . It has good performance of Anti-ablation, thermal shock resistance, erosion resistance and lo ng life. It is good choice for high-end materials for Electronics, semiconductor industry and vacuu m industrial. C/C material has characteristics such as high strength, high stiffless, light weight, high thermal ao nductivity, small expansion coefficient high temOerature resirtance, borrosio n resistance, abrat io n proof sprkng therml shock resistance and more. It is particularly suitable for high temper ature structural part such as durance and support batch pan. Besides successful application in the aerospace domain, the material is also broadly applied to vacuum metallurgy, chemical industry new material, atomic energy, semiconductor, electronic new energy and other domains.
