Ceramic Fiber Blanket Introduction
Ceramic fiber blanket is composed of long, flexible, interwoven fibers manufactured by the “blown”and the “spun” process yielding a strong, lightweight yet durable blanket for applications in a temperature range from 1100°C to 1430°C. Ceramic fiber insulation blanket has the characteristics of high tensile strength for longer life and durability. Ceramic Fiber Blankets contain no binders and are completely inorganic.
Ceramic Fiber Blanket Properties
Excellent thermal stability
Resistance to thermal shock
Low thermal conductivity
Low heat storage
Low shrinkage
Good obstructing voice and mechanism strength
Good springiness for fibers
