Standard Ceramic Fiber Blanket is a lightweight, flexible refractory insulation material made from high-purity alumina-silica fibers through a spun process. With a classification temperature of 1260°C and service temperature up to 1050°C, it offers excellent thermal stability, low thermal conductivity, and superior resistance to thermal shock and chemical attack.
This blanket is white in color, odorless, and suitable for a wide range of high-temperature industrial applications including furnace lining, back-up insulation, and high-temperature sealing. It maintains its structural integrity under extreme conditions while providing excellent energy-saving performance.
