Ceramic Fiber Insulationb Blanket
Fire protection ceramic fiber blanket for steel & iron furnace
Laurel ceramic fiber blanket is composed of long, flexible, interwoven fibers manufactured by the “spun” or “blow” process yielding a strong, light weight yet durable blanket for applications in a temperature range from 1100℃ to 1430℃Ceramic fiber blanket has the heat resistance of a hard refractory with five times better insulation value.
The ceramic fiber insulation blanket is a lightweight, flexible, and highly efficient thermal insulation material made from premium alumino-silicate fibers. Known for its exceptional thermal stability, low heat storage, and resistance to chemical attack, it is an ideal choice for high-temperature applications. Leading ceramic fiber blanket manufacturers produce this material in various densities and thicknesses to meet industrial demands. For convenient installation, it is also available as a ceramic fiber insulation blanket roll.
Whether you require standard sizes or customized solutions, the ceramic fiber insulation blanket from reputable ceramic fiber blanket manufacturers ensures outstanding performance in the most demanding thermal environments.
