Ceramic Fiber Blanket


Blanket is a needled blanket made from our ceramic fiber. The blanket is lightweight, flexible, and available in a wide variety of thicknesses, widths and densities.

IND3180 Blanket resists temperature as high as 2300º. This material is lightweight and has very low thermal conductivity, excellent handling strength, low heat storage, thermal shock resistance and corrosion resistance (commonly used acid and alkali). It also provides excellent sound absorption and excellent fire protection.
