Product Description

Ceramic Fiber Blanket

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.

Features

  • High Temperature Performance: Rated for 1260°C-1430°C.
  • Uniform Needling Structure: High tensile strength and minimal shrinkage.
  • Excellent Thermal Insulation: Conductivity as low as 0.035-0.045 W/m·K.
  • Lightweight: Low heat storage for improved heating efficiency.
  • Sound Absorption: Provides both thermal and acoustic insulation.
  • Eco-Friendly: Non-toxic, chemical-resistant, and recyclable.
