CERAMIC FIBER PRODUCTS

Ceramic fiber insulating board

AGIS ceramic fiber board is a lightweight, low density product ideal for most standard insulating applications. Utilizing a wet forming manufacturing process, the boards combine a blend of alumina-silica ceramic fibers with both organic and inorganic binders to improve handling strength and ensure board integrity at high service temperatures. (Where present, the organic binders burn out between temperatures of 450° and 600°)

Advantages: Low thermal conductivity, low heat storage, stability at high temperatures, excellent resistance to thermal shock, chemical attack, water and oil damage, reduced refractory heat-up and cool-down time, light weight for ease of handling, cutting, drilling, sawing and machining, excellent acoustic insulation 

Properties and characteristics: Continuous use limit: up to 2300°F; melting point: 3200°F; thermal conductivity: 1.53°F per BTU-in/hr/ft2 at 1800°F; density: 16 PCF (pounds per cubic foot); color: white 

Sizes: Thickness: 1/8" to 2"  Sheet size 42" x 48" to 24" x 48"

Applications: With its 16 PCF density, Agis ceramic fiber board is well suited for service conditions characterized by vibrations and mechanical stress. Because of its light weight and relative ease of cutting, Agis ceramic fiber board lends itself well to installation on vertical areas. Also:
