Insulation Graphite Felt
BZNCarbon produces high-quality insulation graphite felt, designed to meet demanding high-temperature environments in industrial and scientific applications. Our felts are available in a variety of grades and formats—soft or rigid—based on the raw materials used and heat treatment levels.
Description
Insulation graphite felt is a high-performance thermal material manufactured from carbon fibers through controlled graphitization. Known for its excellent thermal resistance, lightweight structure, and corrosion protection, it serves as an effective insulator in extremely high-temperature settings.
We offer three types of insulation graphite felt based on the base material:
PAN-based graphite felt
Rayon-based graphite felt
Petroleum coke-based graphite felt
These are available as either soft or rigid felt, and can be processed at temperatures of 1100°C, 1800°C, 2200°C, or 2600°C, with optional purification for ultra-high purity demands.
Application Areas
Thermal insulation in vacuum or inert gas furnaces
Aerospace and aviation components requiring corrosion resistance
Crystal growth and semiconductor processing
Battery and energy storage systems
High-temperature sealing, gasketing, and shielding materials
Nuclear and defense-related technologies
