Ceramic Fiber Blanket

Ceramic Fiber Blanket

Ceramic Fiber Blanket is a high-strength, needle-punched insulating material. Combining long-fiber spinning and double-sided needling processes, it possesses toughness, elasticity, and high tensile strength, resisting tearing both before and after heating.


This product is completely Inorganic and contains no binders, ensuring no smoke or fumes are produced in high-temperature environments. It features excellent thermal shock resistance and low thermal conductivity, making it widely used in industrial furnace linings, high-temperature pipe insulation, and module processing.

  • Excellent thermal stability and thermal shock resistance.
  • High tensile strength; resistant to damage during installation.
  • Low thermal capacity and thermal conductivity for significant energy savings.
