Carbon and graphite insulation materials are engineered to withstand temperatures exceeding 2000°C while maintaining structural integrity. Unlike conventional ceramics, these materials combine high-purity graphite matrices with reinforced carbon fibers to achieve:

Ultra-Low Thermal Conductivity (as low as 0.05 W/m·K at 1000°C).

Exceptional Thermal Shock Resistance, ensuring stability under rapid temperature fluctuations.

Lightweight Properties (density: 0.2–1.2 g/cm³), reducing energy consumption in industrial furnaces by 20–40%28.

CFC Carbon’s products are tailored for diverse applications, including:

Vacuum Furnaces: Rigid graphite felts provide seamless insulation for **** growth systems.

Aerospace: Insulation boards protect critical components in rocket nozzles and re-entry vehicles.

Metallurgy: Linings for aluminum reduction cells enhance durability and reduce maintenance costs.

1. Proprietary Manufacturing Process CFC Carbon’s innovation lies in its Ultra-High-Pressure Impregnation Carbonization (UHPIC) technology, which accelerates production cycles by 50–70% while enhancing material performance:

Preform Fabrication: Carbon fibers (PAN-based T700/T300) are woven into 2D, 2.5D, or 3D architectures tailored to client specifications.

Matrix Densification:

**** Precursor Route: Coal tar pitch or phenolic resin impregnation under 100 MPa pressure.

Gas-Phase Route: Chemical **** Infiltration (CVI) deposits pyrolytic carbon for uniform density (>1.95 g/cm³).

Fast Carbonization: Rapid heating (1000°C/min) to 2500°C minimizes residual stress and optimizes graphitization.

This process ensures higher oxidation resistance and mechanical strength compared to industry standards.
