Ceramic Fiber Board
INSULAC Ceramic fiber board is made from ceramic bulk fiber with a specially formulated binder and produced using vacuum forming technology. The board has excellent toughness and strength, is lightweight, and offers superior thermal shock resistance and anti-stripping properties.
Ceramic fiber board can be widely used for insulation in kiln linings, including around and at the bottom of kilns, as well as in ceramic kiln firing positions, craft glass molds, and other areas. The temperature range varies from LT-1050℃ (1930°F), RT-1260°C (2300°F), to HTZ-1425°C (2600°F). It is available in a wide variety of thicknesses, widths, and densities.
General Characteristics :
- Low heat storage, low thermal conductivity
- Non-brittle material, good elasticity
- High compressive strength &temperature stability
- Excellent wind-erosion resistance, long service life
- Excellent thermal stability and thermal shock resistance
- Continuous production, even fiber distribution and stable performance
- Easily molded or cut, easy to install
- Accurate sizes and good flatness
Typical Applications :
