As a ceramic fiber blanket factory and experienced ceramic fiber blanket supplier in China, Laurel provides standard and specification-based blanket products for industrial customers, refractory contractors, distributors, and equipment manufacturers.

What Is Ceramic Fiber Blanket?

Ceramic fiber blanket is a flexible refractory insulation material made from alumina-silica ceramic fibers. Unlike rigid insulation boards or refractory bricks, it can be folded, wrapped, compressed, and fitted around irregular surfaces.

This flexibility makes ceramic fiber insulation particularly useful when installation space is limited or when the insulation needs to follow curved surfaces.

Laurel ceramic fiber blanket is produced in several grades with different alumina content, density, temperature classification, thermal conductivity, and shrinkage characteristics. Selecting the appropriate grade should be based on the actual operating temperature and installation conditions rather than the classification temperature alone.

Key Features of Ceramic Fiber Insulation

High-Temperature Insulation

Laurel ceramic fiber insulation is available in grades classified from 1260°C to 1430°C. Different grades are designed for different thermal environments, allowing the insulation material to be matched with the operating temperature of the equipment.

The classification temperature should not be treated as the recommended continuous operating temperature. Actual selection should consider furnace temperature, exposure time, thermal cycling, atmosphere, and installation location.

Low Thermal Conductivity

Ceramic fiber blanket provides relatively low thermal conductivity compared with dense refractory materials. The listed values range from approximately 0.06–0.08 W/m·K at 200°C, depending on the grade.

This characteristic makes the material suitable for reducing heat transfer through furnace walls, kiln linings, equipment surfaces, and other high-temperature insulation areas.

Lightweight and Flexible

The blanket is significantly easier to handle than rigid refractory products. It can be cut with standard tools and fitted around curved or irregular surfaces.

The flexible structure is especially useful for expansion joints, furnace repairs, pipe wrapping, and locations where rigid boards are difficult to install.

Low Permanent Shrinkage

The listed grades have permanent linear shrinkage limits of ≤3% under their specified test conditions. Controlling shrinkage is important for maintaining insulation coverage during high-temperature service.

Different Density Options

Laurel supplies ceramic fiber blanket in different density grades, including 64, 96, 128, and selected higher-density specifications.

Higher density can provide improved handling characteristics and tensile strength, while lower-density blanket can be useful where lightweight insulation is preferred. The appropriate density should be selected according to the installation requirements.

Ceramic Insulation Blanket Applications

Ceramic insulation blanket is widely used in industrial thermal equipment where flexible, lightweight insulation is required.

Typical applications include:

• Industrial furnace linings

• Heat-treatment furnaces

• Kiln insulation

• Boiler insulation

• Furnace doors and expansion joints

• Pipe and duct insulation

• Petrochemical heaters and process equipment

• Ceramic and glass kilns

• Steel and metallurgical equipment

• Aluminum processing equipment

• High-temperature equipment maintenance and repair

• Backup insulation behind refractory linings

Metallurgical Industry

Ceramic fiber blanket can be used in heat-treatment furnace linings, tundish and ladle insulation, furnace doors, and other high-temperature areas where lightweight flexible insulation is required.

Petrochemical Industry

Typical applications include insulation around pipes, ducts, heaters, reformers, and selected process equipment. The grade should be selected according to temperature, atmosphere, and installation requirements.

Power Generation

Ceramic fiber insulation can be used around boilers, ducts, expansion areas, and selected high-temperature equipment where flexible thermal insulation is required.

Ceramic and Glass Industry

Kilns, furnace linings, expansion joints, burner areas, and maintenance applications can use ceramic fiber blanket where its flexibility and low thermal conductivity provide installation advantages.

Ceramic Fire Blanket: What Does It Mean?

The term ceramic fire blanket is sometimes used when buyers are searching for high-temperature ceramic fiber insulation. In industrial refractory applications, the more precise product name is ceramic fiber blanket.

Industrial buyers should distinguish ceramic fiber insulation used for furnaces and thermal equipment from consumer-oriented fire blankets or other fire-protection products. The material specification, temperature classification, density, and intended application should always be confirmed before ordering.

Ceramic Wool Blanket

Ceramic wool blanket is another term sometimes used to describe flexible ceramic fiber insulation. In industrial refractory applications, ceramic fiber blanket is the more commonly used technical product term.

Laurel supplies alumina-silica ceramic fiber insulation in different grades and densities for high-temperature industrial applications. Buyers should evaluate the chemical composition, classification temperature, density, thermal conductivity, and shrinkage data when comparing different ceramic wool blanket products.
