Graphite Felt / Carbon Fiber

Advanced Thermal Insulation: Graphite Felt & Carbon Fiber

Offering unmatched thermal insulation efficiency at temperatures up to 2800°C, our high-purity graphite felt and carbon fiber insulation materials are designed for inert gas and vacuum furnace environments. Their extremely low thermal conductivity reduces power consumption and optimizes furnace temperature stabilization. These flexible and rigid insulation systems work synergistically with internal furnace components like Graphite Heaters and external structures.

Low Thermal Conductivity

Dramatically cuts energy losses and maintains precise internal temperature fields.

High Chemical Purity

Halogen-purified options preventing gas outgassing and furnace contamination.

Structural Versatility

Easily held in place with Graphite Fasteners or graphite foil facings.
