Ceramic Fiber Boards from CeraMaterials

What is Ceramic Fiber Board?

Ceramic Fiber boards provide a rigid solution for ceramic fiber insulation. The boards are manufactured through a wet forming process using alumina-silica fibers and binders. Standard board grades are standard, high purity, and zirconia. Boards are available in a variety of temperature ratings, dimensions, and custom vacuum formed shapes. If you are looking for a board not listed or a custom fabrication, please contact us directly.

Low Density Vs. High Density

Low density boards are slightly better insulators, but they are not as durable and heavy as high density. Our office always recommends high density when drilling, machining, or rigidizing ceramic fiber boards. If you have further questions in regards to your specific application, contact us.

Stocking Locations.

Our boards are available domestically and internationally. Some of our domestic locations are listed below, please note that inventory and pricing may vary. Full pallet orders do qualify for 10% discounts. Please contact us directly for this option.

Benefits

  • High temperature stability.
  • Excellent strength and hardness.
  • Low thermal conductivity, sound transmission, and heat storage.
  • Uniform density and excellent resistance to thermal shock and chemical attack.
  • Excellent rigidity and modulus of rupture make the boards strong and self-supporting, yet relatively lightweight and easy to cut or machine.
  • Resistant to oxidation and reduction.
  • Permits fast thermal cycling without cracking or spalling.
  • Resists penetration by molten aluminum and other non-ferrous metals.

What is Mineral Wool Board?

Mineral Wool Boards provide a rigid solution for high temperature insulation applications rated to a maximum temperature of 1900℉ on the hot surface of an enclosed panel. The boards are manufactured using mineral fibers and organic binders. Boards are not to be subjected to direct contact with a flame as a hot face, but does offer a cost effective solution if your operating temperatures are < 1900℉. Typically, the boards are used as a secondary insulator. Mineral Boards are available in a variety of dimensions, and custom shapes. If you are looking for a board not listed or a custom fabrication, please contact us directly.

Additionally, when the boards are heated above 500℉ smoke is generated from the binder burning out of the board. This only occurs on the first high temperature run and will disperse. To minimize smoke on initial start-up, the heat should be controlled at 20℉ per minute to allow the binder to dissipate with small temperature increases. Ignition loss of the binder does not adversely affect the insulation value of the boards.

Benefits

  • Excellent insulation efficiency and good strength.
  • Low thermal conductivity and asbestos free.
  • Simple to use, easy to cut and handle.
  • Boards do not absorb water or hold moisture.
