Thermal Ceramics TR-19HS Block Insulation
Categories:	Ceramic
Material Notes:	TR-19HS Block is an asbestos-free insulation products, manufactured from vermiculite granules and high temperature bonding materials.TR-19HS Block is a high strength structural insulation material, suitable particularly where mechanical loads are present. This block product has very low shrinkage to its 1900°F (1040°C) operating temperature limit and is resistant to cryolite vapor conditions. Features: Low thermal conductivity Block construction 36" x 12" Good high temperature strength Variety of thicknesses up to 7” Resistant to cryolite vapors Applications: Side and end wall insulating material in carbon baking pits Backup insulation in aluminum pot cells, reheat and pusher furnaces, copper reverberatory furnaces, and oil-fired water tube boilers Curved Block Interior and exterior use on bustle pipes, hot air pipes, stacks and other curved or circular equipment Information provided by Thermal Ceramics Data has not been recently verified.
