Characteristics of Ceramic Fiber:

  • Low Thermal Conductivity: Ceramic fibers boast low thermal conductivity, making them ideal for efficient heat insulation.
  • Low Density: With their lightweight nature, ceramic fibers offer easy handling and application.
  • Low Heat Capacity: The low heat capacity of ceramic fibers allows for quick response to temperature changes.
  • Good Processing Performance: These fibers are soft and easy to cut, ensuring seamless processing with strong continuity.
  • Sound-Absorbing Performance: Ceramic fibers possess excellent sound-absorbing properties, making them suitable for high-temperature sound absorption.
  • Chemical Stability: With exceptional chemical stability, ceramic fibers are highly resistant to corrosion, except in the presence of strong alkali, fluorine, and phosphate.
  • Good Thermal Shock Resistance: Ceramic fibers can withstand sudden temperature changes without damage.
  • Insulation Performance: Enjoy excellent insulation performance, with volume resistivity of approximately 1×1013Ω·cm at room temperature and 6×108Ω·cm at 800°C.
  • Reflectivity to Light Waves: Ceramic fibers exhibit high reflectivity to light waves within wavelengths of 1.8~6.0 μm.

Ceramic Fiber Paper:

Ceramic fiber paper is produced through a process of beating, papermaking, sizing, and drying ceramic fiber bulk, resembling traditional wet papermaking. This type of ceramic fiber paper offers exceptional high-temperature resistance, thermal performance, construction performance, as well as resistance to melting and penetration. It is a versatile material suitable for deep processing (multi-layer composite, punching, etc) and finds extensive use as cast gaskets in the construction and glass industries.
