Short Fiber Insulation Felt is a high-performance carbon-based insulation material engineered for extreme-temperature industrial environments. Composed of carbon fibers bonded with a carbon matrix, it forms rigid plates, cylinders, or custom 3D-machined shapes. Designed for vacuum and inert-gas furnaces, it delivers exceptional thermal stability and electrical insulation while excelling in high-purity processes like semiconductor crystal growth and advanced ceramics sintering.
