Ceramic Fiber Blanket
HIGH TEMPERATURE INSULATION

Ceramic Fiber Blanket

Standard ceramic fibers are made from inorganic materials, primarily Alumina, Silica & Zirconia, with long refractory fiber, which are binder free and are needled leading to very high thermo stability. Under normal circumstances ceramic fiber can be applied at 1260°C. It has very low thermal conductivity.

Ceramic Fiber Blanket is a lightweight, flexible, and high-performance insulation material engineered for extreme temperature applications. It offers outstanding thermal insulation, low thermal conductivity, excellent thermal shock resistance, and exceptional fire protection. Widely used in furnaces, kilns, boilers, ovens, and industrial pipelines.
