Ceramic Fiber Blanket for High-Efficiency Industrial Furnace Insulation

Ceramic fiber blanket is a lightweight, resilient, and highly efficient insulation material designed for industrial furnaces operating between 1000°C and 1600°C. Manufactured from alumina-silicate or zirconia-enhanced fibers, it offers excellent thermal insulation, low heat storage, and outstanding resistance to thermal shock. Its flexibility and easy installation make it suitable for a wide range of high-temperature applications, including steel furnaces, ceramic kilns, petrochemical units, heat treatment chambers, and energy-saving retrofits.

Thermaxcel's ceramic fiber blankets are available in multiple temperature grades-1260°C, 1360°C, 1400°C, and 1600°C-with densities up to 160 kg/m³, providing stable long-term performance in demanding environments.

Technical Description

Ceramic fiber blanket is produced through a stream-blowing or spun fiber forming process, where molten alumina-silicate materials are fiberized into long, continuous fibers. These fibers are then mechanically needled to create a three-dimensional structure that provides:
low density
strong tensile strength
high elasticity
minimal shrinkage
enhanced thermal stability
Different fiber compositions (standard, high-purity, high-alumina, zirconia-containing) enable the blanket to perform reliably under different temperatures and atmospheres.

Classification Temperature vs. Continuous Use Temperature

A common misunderstanding is that "classification temperature = working temperature."

Grade	Classification Temp	Continuous Use Temp
1260°C Standard / HP	1260°C	1050–1150°C
1350°C HA	1350°C	1150–1200°C
1400°C / 1430°C	1400–1430°C	1200–1270°C
1600°C Zirconia Fiber	1600°C	1350–1450°C

FAQ

Q1:What is the difference between 1260°C and 1400°C ceramic fiber blankets?

A1: Higher temperature blankets contain more alumina and have lower shrinkage at elevated temperatures.

Q2: Can ceramic fiber blanket contact molten metal?

A2: Standard grades cannot; zirconia fiber is recommended for extreme environments.

Q3: How do I select the correct density?

A3: 96 kg/m³ for general insulation, 128 kg/m³ for furnace linings, 160 kg/m³ for high load areas.

Q4: Does ceramic fiber blanket release dust?

A4: Minimal dust during installation; once installed, dust release is extremely low.

Q5: Can it be used in reducing atmospheres?

A5: Yes. High-purity and zirconia-containing grades are stable in reducing, oxidizing, and neutral conditions.

Q6: What is the typical shrinkage rate?

A6: 1260°C fibers shrink 2–3% at working temperature; zirconia fibers <1%.

Q7: Is it suitable for lining replacement?

A7: Yes. It is lightweight and easy to retrofit into existing furnace structures.

Q8: What thickness is commonly used?

A8: 25, 50, and 75 mm depending on design temperature and insulation requirements.
