Thermal Ceramics Kaowool 17C High Temperature Boards
Categories:	Ceramic; Oxide; Aluminum Oxide
Material Notes:	Kaowool 17C is processed using a blend of high purity ceramic fibers, high temperature alumina fibers and binders. This combination produces a product with improved high temperature stability. Kaowool 17C exhibits excellent shrinkage and mechanical strengths after firing for temperatures up to 2900°F (1593°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.
