The Ultimate Guide to Ceramic Fiber Cloth for High-Temperature Insulation
December 11 , 2025
A ceramic fiber cloth is one of the most versatile and reliable high-temperature insulation materials used across industrial sectors today. Known for its exceptional heat resistance, flexibility, and thermal stability, ceramic fiber cloth plays a vital role in furnace insulation, fire protection, welding safety, and equipment protection.
What Is Ceramic Fiber Cloth?
Ceramic fiber cloth is a woven textile made from alumino-silicate ceramic fibers combined with reinforced materials such as fiberglass or stainless-steel wire. This combination allows the cloth to maintain structural integrity even under extreme temperatures.
Material Composition & Manufacturing Process
Ceramic fiber cloth typically includes:
47–53% SiO₂ (Silica)
47–53% Al₂O₃ (Alumina)
Woven structure for strength and flexibility
Optional reinforcement using:
Fiberglass thread (to 550°C)
Stainless steel wire (to 1050°C)
Key Performance Features
Withstands continuous heat up to 1000°C
Low thermal conductivity
Non-combustible
Excellent mechanical strength
Resistant to thermal shock and vibration
How Ceramic Fiber Cloth Works in Thermal Insulation
High-Temperature Resistance Mechanism
Ceramic fibers are inorganic and refractory, meaning they won’t melt, burn, or degrade under high heat. This makes ceramic fiber cloth ideal for harsh thermal environments.
Heat Shielding, Fire Protection & Energy Saving
The cloth creates an insulating barrier that:
Blocks radiant heat
Reduces heat transfer
Protects equipment from fire and hot surfaces
Improves energy efficiency in industrial processes
Applications Across Industries
Foundry, Metallurgy & Furnace Insulation
Used to insulate:
Kiln doors
Furnace linings
Ladles
Gaskets
Expansion joints
Petrochemical & Power Generation
Ideal for:
Heat exchangers
Pipe protection
Pump housings
Turbine insulation
Fireproofing, Welding & Industrial Protection
Ceramic fiber cloth is commonly used as:
Welding blankets
Fire curtains
High-temperature protective shields
Spray splash protection
Benefits of Using Ceramic Fiber Cloth
Excellent Thermal Stability
Ceramic fiber cloth can handle rapid heating and cooling cycles without cracking or degrading.
Lightweight & Flexible Structure
Easy to cut, fold, sew, and mount—making installation simple across various applications.
Chemical & Corrosion Resistance
Ceramic fibers resist most acids, alkalis, and corrosive chemicals, except hydrofluoric acid and strong alkaline environments.
