High Temperature Resistant Ceramic Fiber Blanket, Refractory Insulation Material for Industrial Kilns & Furnaces

Ceramic fiber blanket is a flexible, refractory, and thermal-insulating material composed primarily of aluminum silicate fibers. It is manufactured through high-temperature melting followed by fiberization—using either spinning or blowing techniques—and a double-sided needle-punching process.

Its chemical composition is dominated by alumina and silica; depending on the grade, the alumina content ranges from 40% to 55%, with the option to enhance temperature resistance through the addition of zirconia. Free of organic binders, the material is characterized by low weight, low heat capacity, and low thermal conductivity.

It is suitable for long-term use within a temperature range of approximately 1000°C to 1350°C and is widely used for industrial furnace linings and backings, furnace door seals, and high-temperature pipe insulation.

1. Excellent high-temperature resistance, classification temperature up to 1260°C, stable performance for industrial kiln continuous operation.
2. Low thermal conductivity, effectively reduce heat loss and save fuel cost for furnace equipment.
3. Light weight with low heat capacity, fast heating and cooling, less thermal load on kiln structure.
4. Good thermal shock resistance, not easy to crack or peel under frequent temperature changes.
5. Flexible and easy to cut, install and construct, suitable for irregular kiln lining and pipe wrapping.
6. Stable chemical inertness, resistant to most corrosion except strong acid and strong alkali.
