Ceramic fiber blanket is white in color, regular in size, integrated with heat insulation, and heat preservation functions, and does not contain any additives. Ceramic fiber blankets are made from spun ceramic fibers that have been needle punched to provide excellent handling strength for high-temperature insulation applications. It can maintain good tensile strength, and toughness when used in neutral and oxidizing atmospheres.
