Ceramic Fiber Blanket (1)

What is Ceramic Fiber Blanket Insulation?

Ceramic Fiber Blanket Insulation is manufactured from spun ceramic fiber and is needled to provide exceptional handling strength for high-temperature insulation applications. Ceramic Insulation Blanket is typically offered in three standard grades referred to as commercial, High-Purity, and Zirconia grade. All grades are lightweight and thermally efficient resulting in a material that has the advantage of low heat storage and complete resistance to thermal shock. Blankets are produced in varying dimensions, temperature ratings, and for different applications. Our office also supplies a Bio-Soluble blanket which is environmentally friendly. If you don’t see a specific blanket listed, please contact us directly and we will be happy to provide a custom quote.

Operating at Higher Temperatures?

Ceramic Fiber Blanket Insulation is manufactured from polycrystalline mullite wool (PCW) rated to a temperature of 3000℉ (1649℃) is now stocked. This grade of Ceramic Insulation Blanket contains no binder, additives, or shot content. Material is RCF free and resistant to most corrosive agents in both oxidizing and reducing atmospheres. This material is highly specialized for the most demanding and extreme temperature requirements.

Complex Shapes & Gas Velocities

Ceramic Fiber Blanket Wet Wool (WW) is specifically manufactured for insulating complex shapes and services under high hot gas velocities. Material is permeated with inorganic bonding agents and packaged in a clear polyethylene bag to retain the wet binder during shipping and storage. The manufacturing process results in flexible insulation that can be formed to complex shapes in place and air dries to form a hard, rigid structure. Additionally, the material can be cured by immediate exposure to temperature in application. Material has a dry density of 12-18 lbs/ft3 (190-290 kg/m3).
