Thermal Ceramics Kaowool 2800M High Temperature Board
Categories:	Ceramic; Oxide; Aluminum Oxide
Material Notes:	Kaowool 2800M is processed using a blend of high purity ceramic fibers and high temperature mullite fibers. This combination produces a product with improved high temperature stability. Kaowool exhibits excellent shrinkage and mechanical strengths after firing for temperatures up to 2800°F (1538°C). Applications: Appliance and heat processing Backup insulation to dense refractories Bullnose tiles Burner blocks Combustion chamber construction Expansion joint material Flue and chimney linings Furnace components Furnace door linings Furnace, kiln, and oven hot face linings Glass regenerator insulation Heat shields High temperature gaskets and seals Peep door frames and plugs Shapes in ammonia reformers Information provided by Thermal Ceramics Data has not been recently verified.
