Complete Ceramic Fiber Solutions for High-Temperature Insulation

Ceramic fiber insulation products are manufactured from high-purity alumina-silicate fibers produced by melting and fiberizing a blend of alumina and silica. These products offer an outstanding combination of low thermal conductivity, high-temperature resistance, thermal shock resistance and light weight, making them the material of choice for industrial furnace and kiln insulation.

Our product range includes ceramic fiber cloth, tape and rope (textile products for sealing, wrapping and gasketing), ceramic fiber blanket (needled blanket for furnace linings and backup insulation), ceramic fiber board (rigid board for hot-face and structural insulation), and ceramic fiber paper (thin paper for gasketing, parting and electrical insulation). Each product form is available in multiple grades including standard (1260°C), high-alumina (1350°C), and zirconia-containing (1430°C) to suit different temperature requirements.

We supply ceramic fiber insulation products for overseas distributors, industrial buyers, furnace manufacturers, maintenance companies and OEM customers, with different grades, dimensions, densities and custom fabrication available according to specification.

    FAQ

    Frequently Asked Questions About Ceramic Fiber Insulation

    What is ceramic fiber insulation?
    Ceramic fiber insulation is a high-temperature insulation material made from alumina-silicate fibers. It is available in multiple forms including cloth, tape, rope, blanket, board and paper, used for furnace linings, high-temperature sealing and thermal management.
    What is the maximum temperature of ceramic fiber products?
    Standard-grade ceramic fiber products have a classification temperature of +1260°C. High-alumina grades reach +1350°C, and zirconia-containing grades reach +1430°C. Special high-purity grades can reach +1600°C.
    What is the difference between ceramic fiber and fiberglass?
    Ceramic fiber withstands much higher temperatures (+1260°C to +1430°C) compared to fiberglass (+550°C to +650°C). Ceramic fiber also has lower thermal conductivity at high temperatures, making it more effective for furnace insulation.
    What forms of ceramic fiber products are available?
    We supply ceramic fiber cloth, tape, rope, blanket, board and paper. Each form is suited to different applications: blanket and board for furnace linings, cloth/tape/rope for sealing and wrapping, and paper for thin gaskets and parting.
    What sizes and thicknesses are available?
    Cloth thickness ranges from 1.5 mm to 6 mm. Blanket thickness ranges from 6 mm to 50 mm with densities from 64 to 160 kg/m³. Board thickness ranges from 10 mm to 100 mm. Paper thickness ranges from 0.5 mm to 13 mm. Custom dimensions are available.
    Is ceramic fiber safe to use?
    Yes. Modern ceramic fiber products, especially bio-soluble grades, are designed to be safe when handled properly. Appropriate protective equipment (gloves, dust mask) should be used during installation.
    Can ceramic fiber products be used in boilers and kilns?
    Yes. Ceramic fiber blanket and board are widely used for boiler insulation, kiln linings, and high- temperature furnace applications. Cloth, tape and rope are used for seals and expansion joints in these applications.
    Is ceramic fiber insulation RoHS compliant?
    RoHS compliance can be provided for applicable grades and documentation requirements. Please confirm when requesting a quotation.
    What information do you need for a quotation?
    Please provide the required product form (cloth, tape, rope, blanket, board or paper), grade/temperature, dimensions (thickness, width, density), quantity, and any special requirements.
