Ceramic Fiber Paper

Ceramic Fiber Paper

Ceramic Fiber Paper is a refractory paper manufactured using a special paper-making process. Composed of bio-soluble bulk fibers, binders, and additives, it offers a uniform texture and exceptional flexibility.


This product is easy to handle and can be wrapped, cut, or molded with ease. It is widely used for high-temperature gaskets, thermal sealing, and as a casting parting medium. Being part of the AES (Alkaline Earth Silicate) system, it complies with environmental and safety standards.

  • Excellent Thermal Shock Resistance: Withstands rapid temperature changes.
  • High Flexibility: Easily wraps around complex equipment shapes.
  • Low Thermal Conductivity: Effectively blocks heat transfer.
  • Easy Installation: Exceptionally easy to cut and punch.
