Ceramic Fibre Felt: Reliable High-Temperature Insulation for Industrial Projects

What Is Ceramic Fibre Felt
Ceramic fibre felt is a lightweight, non-woven refractory insulation material manufactured from high-purity alumina-silica ceramic fibres, bonded with low-content organic binders for stable handling. Unlike rigid refractory boards, it features soft, porous fibre structure with outstanding heat retention and flexibility. Standard grades support continuous working temperature up to 1260°C, while high-purity versions can resist up to 1430°C. It is asbestos-free, non-combustible and engineered for long-term thermal management in harsh high-heat working environments.

Key Performance Benefits
Low thermal conductivity is its core advantage, which effectively cuts heat loss and reduces fuel consumption for your heating equipment. It delivers excellent thermal shock resistance and minimal thermal shrinkage after repeated heating cycles. The soft, drapable texture fits irregular surfaces, curved pipes and complex furnace structures, making cutting and on-site installation fast and simple. It also maintains stable performance against most weak acids, alkalis and oil vapour, suitable for long-cycle industrial operation without frequent replacement. Our ceramic fibre felt comes in standard thicknesses and custom sizes to match different lining, sealing and backup insulation requirements.

Common Industrial Applications
This refractory felt is widely adopted across multiple heavy industries. It serves as backup lining for industrial kilns, furnaces and heat treatment ovens in metallurgy, steel and ceramics sectors. It works as expansion joint filling, high-temperature gasket and molten metal insulation barrier for non-ferrous melting lines. Petrochemical, power boiler and exhaust pipeline insulation projects also choose it for heat shielding and fire protection. Many customers use it for removable thermal covers, furnace door seals and lab high-temperature equipment insulation.
