Product Description

Ceramic Fiber Blanket for Furnace Lining

The 25mm Ceramic Fiber Blanket is a high-temperature alumina-silicate insulation material widely used in industrial furnaces, heating equipment, boilers, kiln linings, chimney insulation, and thermal processing systems.

It is manufactured through a continuous needled process, ensuring excellent fiber strength, uniform texture, low thermal conductivity, and superior temperature resistance. The product is available in 1260°C / 1350°C / 1430°C classification grades and suitable for both new furnace construction and maintenance.

Key Features

High Temp Performance: Rated for 1260°C-1430°C.

Tensile Strength: Uniform fiber needling structure ensures durability.

Thermal Insulation: Conductivity as low as 0.035-0.045 W/m·K.

Lightweight: Improves furnace heating efficiency and low heat storage.

Sound Absorption: Provides both thermal and acoustic insulation.

Eco-Friendly: Non-toxic, non-corrosive, and chemical-resistant.

Applications

Industrial Furnaces & Kilns: Furnace lining & back lining, continuous annealing furnaces, heat treatment equipment, kiln car insulation.

Boilers & Thermal Equipment: Boiler door insulation, burner area protection, chimney and flue insulation.

Refractory Construction: Expansion joint filling, back-up insulation behind refractory bricks, insulation layer under ceramic fiber modules.

Building & Acoustic Uses: Fire protection panels, sound insulation wall panels, HVAC duct insulation.

Frequently Asked Questions

Is 25mm thickness suitable for furnace lining?

Yes - it is commonly used as a high-efficiency hot-face or back-up insulation layer in various industrial furnace designs.

Which density should I choose: 96 or 128 kg/m³?

96 kg/m³ is economical and lightweight, while 128 kg/m³ offers higher tensile strength and improved thermal insulation properties for demanding applications.

Can you produce 50mm or other custom thicknesses?

Yes, the thickness, density, and roll length can all be customized to meet specific engineering requirements.

What is the maximum operating temperature?

Depending on the specific grade chosen (Standard, High Purity, or Zirconia), the classification temperature reaches up to 1430°C.

Do you offer other related refractory products?

Yes, a complete ceramic fiber product system is available, including modules, boards, paper, and textiles.

Is this material resistant to chemicals?

Ceramic fiber blankets have excellent chemical stability and resist most corrosive agents, except hydrofluoric and phosphoric acids and strong alkalies.
