Rayon Based Rigid Graphite Felt
BZNCarbon manufactures high-performance rayon based rigid graphite felt, developed from soft rayon felt through high-temperature graphitization and structural reinforcement. Our products are known for their high purity, superior mechanical strength, and excellent thermal insulation capabilities, especially in vacuum or inert atmospheres.
Description
Rayon based rigid graphite felt is made by graphitizing soft rayon felt and compressing it into a rigid board or custom shape. Depending on the application, it can be laminated with CFC (Carbon Fiber Composite) on one or both sides, or graphite foil on one or both surfaces. These options are available upon customer request.
This material is ideal for extremely high-temperature applications, with heat treatment levels of 1800°C, 2200°C, and 2600°C.
Application Areas
Vacuum furnaces and high-temperature heat shields
Thermal insulation in crystal growing systems
Semiconductor and solar panel production
Aerospace and nuclear insulation systems
Energy storage and advanced battery systems
