REFRACTORY BOARD TYPES ZIRCAL-18, ZIRCAL-45 AND ZIRCAL-95 ZIRCAR Refractory Comoposites, Inc. provides a variety of non-asbestos calcium silicate structural insulations that combine high strength and excellent thermal insulating characteristics for use in a variety of heat processing, fire protection and electrical resistance applications. The unique calcium silicate structure provides excellent thermal shock resistance as evidenced in its typical use as a direct contact board for non-ferrous metals and in fire training burn rooms. They are fire resistant to temperatures approaching 2000°F. They also exhibit low thermal conductivities that remain relatively constant over a broad range of operating temperatures. • Thermal shock resistance and stability - will withstand continuous heat up to its full temperature limit. • A consistently low thermal conductivity means high energy savings. • High structural strength at elevated temperatures - retains full integrity across a broad range of temperatures. • Incombustible - ideal for personnel protection, cable trays, fire doors, and marine applications. • Easily machined to tight tolerances with conventional tooling. ZIRCAL-95 is ideal for machining to tight tolerances. Uses include insulation for Annealing furnaces, Blast furnace stoves, Bustle pipes, Car tops, Forge furnaces, Glass lehrs, Heat treating, Hi-temp mains and flues, Industrial boilers, Kiln cars, Kilns, Laboratory furnaces, Marine boilers, Ovens, Pot furnaces, Petrochem heaters, Pipe supports, Regenerators, Reheat furnaces, Reverberatory furnaces, Roasters, Soaking pits, and Utility boilers. ZIRCAL-45 boards are used in a variety of heat insulating process, fire protection and as machined parts. ZIRCAR Refractory Composites, Inc. P.O.

REFRACTORY BOARD TYPES ZIRCAL-18, ZIRCAL-45 AND ZIRCAL-95 ZIRCAL-18 Type ZIRCAL-18 Refractory Board is a high temperature calcium silicate block insulation with excellent mechanical properties and stability up to 1100°C(2000°F). Its high thermal insulating value makes it ideal for many fireproofing and heat processing equipment applications. ZIRCAL-18 is designed to serve as a backup insulation for any refractory construction, such as insulating fire brick, dense refractory brick, castable, gunning mix, plastic refractory or ceramic fiber. ZIRCAL-18's high refractoriness and strength help...
