Thermal Ceramics TR-19 Block Insulation
Categories:	Ceramic
Material Notes:	TR-19 Block is an asbestos-free insulation products, manufactured from vermiculite granules and high temperature bonding materials. Because of its low conductivity, TR-19 Block is an economical, energy saving insulation. It exhibits minimal shrinkage at its 1900°F (1040°C) temperature limit, and will not readily decompose even when exposed directly to flame or 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 Curved Block Designed for curved or circular equipment TR-19 recommended for temperatures up to 1900°F 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.
