Insulations That Withstsand Extreme Temperatures

How Do Ceramic Fibers To Be Produced?

Ceramic fibers are manufactured from materials like aluminum silicates, zirconium silicates, and aluminoborosilicates. They are composed of very fine fibers that produce a low thermal conductivity, making them effective insulators.

Ceramic fiber board insulation is made of high-purity aluminum silicate fibers that are bonded together with a high-temperature organic or inorganic binder. Ceramic fiber resistant boards are rigid and come in panel form with tongue and groove edges for easy installation. They provide great heat and thermal shock resistance and are often used for lining kilns, furnaces, ovens and other industrial equipment. Ceramic fiber boards are a good economic option for most high-temperature insulation applications.

Top 3 Ceramic Insulation Options

Ceramic fiber board and ceramic fiber insulation can withstand very high temperatures, making them ideal options for industrial insulation applications. These insulations are fire resistant and can resist temperatures up to 2,300°F. There are a few ceramic insulation options:

  • Ceramic fiber blanket are flexible forms of ceramic fiber insulation made from similar materials as the boards. Ceramic fiber blankets can be installed in spaces that are hard to access with rigid boards. They are used to insulate pipes, ducts, vessels and equipment up to 2,300°F. The blankets are also resistant to corrosion from most chemicals and are noncombustible.
  • Ceramic fiber modules are pre-formed to a specific shape to match the hardware they are insulating. This can help streamline installation and reduce field labor costs. Modules are often used to insulate extruders, dryers, ovens and induction furnaces.
  • Ceramic fiber insulation is an excellent choice for applications requiring high-temperature, fire and thermal shock resistance, such as industrial furnaces and ductwork insulation. The rigid boards, flexible blankets and pre-formed modules provide reliable insulation solutions for extreme heat.

Good Features Of Ceramic Fiber Insulation

  • Ceramic fiber insulation is noncombustible and self-extinguishing. It will not fuel a fire and helps prevent the spread of flames. It has a zero flame spread rating.
  • Ceramic fiber board insulation and blankets are lightweight but very durable. They can remain stable for decades in high temperature applications with little degradation.
  • Ceramic fibers are chemically inert and withstand attack from most industrial chemicals and corrosive environments. They are resistant to moisture, acids and bases.
  • Ceramic fiber insulation provides excellent insulation against both heat and cold. It traps still air within its micro-porous structure, reducing heat transfer by conduction and convection.
