Ceramic fiber blanket product showcase with high-temperature furnace background

Overview

Looking for a reliable high-temperature insulation material for furnaces, kilns, petrochemical equipment, industrial piping, and thermal processing systems?

Airgeltech Ceramic Fiber Blanket is a lightweight, flexible refractory insulation material manufactured from alumina-silica ceramic fibers through a mechanical needling process.

Designed for demanding thermal environments, ceramic fiber blanket combines low thermal conductivity, low heat storage, thermal shock resistance, and installation flexibility. It is widely used in industrial furnaces, process heaters, kilns, petrochemical facilities, power generation systems, and high-temperature piping applications.

Available in multiple temperature classifications and densities, Airgeltech ceramic fiber blanket solutions help support reliable thermal performance in elevated-temperature operating environments.

What Is Ceramic Fiber Blanket?

Ceramic fiber blanket is produced from high-temperature alumina-silica fibers that are mechanically entangled through a needling process to form a resilient insulation blanket.

Unlike rigid refractory materials, ceramic fiber blanket offers:

  • ▸High-temperature resistance
  • ▸Excellent flexibility
  • ▸Reduced thermal mass
  • ▸Thermal shock resistance
  • ▸Easy handling and installation
  • ▸Low structural loading

The long-fiber blanket structure allows installation around pipes, expansion joints, furnace walls, equipment surfaces, and irregular thermal systems.

Key Features

High-Temperature Resistance

Available ceramic fiber blanket classifications include 1260°C, 1350°C, and 1430°C for different furnace, kiln, process-heater, and refractory insulation requirements.

Low Thermal Conductivity & Low Heat Storage

The porous fiber structure helps reduce conductive heat transfer and contributes to improved energy efficiency. Compared with dense refractory products, ceramic fiber blanket stores significantly less heat, helping improve heating and cooling efficiency.

Thermal Shock Resistance & High Tensile Strength

Its flexible structure performs well under repeated thermal cycling conditions. The needled-fiber construction provides strength and mechanical integrity during handling and installation.

Flexible Installation

Ceramic fiber blanket can be:

  • ▸Wrapped around industrial piping
  • ▸Installed behind refractory linings
  • ▸Applied to furnace walls and roofs
  • ▸Used in expansion joints
  • ▸Incorporated into modular insulation systems

Chemical Stability

Ceramic fiber blanket provides stable thermal performance across many industrial operating environments. Suitability should always be evaluated for applications involving aggressive chemicals, molten materials, or specialized atmospheres.

Ceramic Fiber Blanket vs Aerogel Blanket

Both materials are widely used in thermal insulation applications, but they address different engineering priorities.

Comparison Item Ceramic Fiber Blanket Aerogel Blanket
Primary Application Refractory and high-temperature systems High-performance industrial insulation
Thermal Conductivity Low Typically lower
Required Thickness Generally higher Generally lower
Space Saving Moderate Excellent
Flexibility Excellent Excellent
Temperature Capability Excellent Excellent
Initial Material Cost Generally lower Generally higher

Ceramic fiber blanket is commonly selected for high-temperature refractory systems, while aerogel blanket is often preferred where low thermal conductivity and reduced insulation thickness are critical requirements.

How to Select the Right Ceramic Fiber Blanket

1. Operating Temperature

Select the appropriate product grade based on actual operating conditions. Classification temperature should not automatically be treated as recommended continuous-use temperature.

2. Density Selection

Typical available densities include 64 kg/m³, 96 kg/m³, and 128 kg/m³. Higher densities generally provide improved mechanical stability.

3. Thickness Selection

Required thickness should be determined according to: heat-loss calculations, surface temperature targets, energy-efficiency requirements, and available installation space.

4. Installation Environment

Consider furnace atmosphere, chemical exposure, gas velocity, thermal cycling, and mechanical loading when selecting insulation materials.

Frequently Asked Questions

What is ceramic fiber blanket?

Ceramic fiber blanket is a flexible refractory insulation material manufactured from needled alumina-silica ceramic fibers for high-temperature thermal insulation applications.

What temperature grades are available?

Airgeltech ceramic fiber blanket products are available in 1260°C, 1350°C, and 1430°C classification grades.

Is classification temperature the same as working temperature?

No. Classification temperature is a standardized product rating and should not automatically be interpreted as the recommended continuous operating temperature.

What density ceramic fiber blanket should I choose?

Typical densities include 64, 96, and 128 kg/m³. Selection depends on application requirements and insulation design considerations.

What thickness ceramic fiber blanket is recommended?

Required thickness should be determined through engineering calculations based on operating temperature, heat-loss targets, and installation constraints.

What is the difference between 1260°C and 1430°C ceramic fiber blanket?

1430°C grades typically contain zirconia and are designed for higher-temperature thermal systems. 1260°C grades are widely used in general industrial insulation applications.
