Rigid Graphite Felt Parts
BZNCarbon produces high-quality rigid graphite felt parts engineered for use in extreme thermal, chemical, and mechanical environments. Our parts are manufactured from both PAN-based and Rayon-based rigid graphite felt, available in board, plate, disc, or custom-machined shapes to meet customer-specific technical and dimensional requirements.
We offer optional CFC (Carbon Fiber Composite) or graphite foil surface reinforcement—on one or both sides—based on user needs. Our products are processed at 1800°C, 2200°C, or 2600°C, ensuring superior thermal and mechanical stability.
Description
Rigid graphite felt parts are developed by high-temperature graphitization of soft felt followed by structural reinforcement into monolithic rigid shapes. These parts offer low thermal conductivity, high carbon purity, and excellent structural integrity at extreme temperatures. They are customizable in both shape and thickness for specialized industrial applications.
Application Areas
Vacuum furnace insulation and heat shields
High-temperature gas or molten metal filtration
Fuel cell porous electrodes
Catalyst supports and chemical-resistant linings
Composite reinforcement for carbon/carbon (C/C) materials
Solar, aerospace, semiconductor, nuclear, and energy storage systems
