REFRACTORY BOARD TYPES ZIRCAL-18, ZIRCAL-45, ZIRCAL95, ZIRCAL-60 and ZIRCAL-A ZIRCAR Refractory Composites, 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. 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-18 is the ideal choice for efficient insulation of kilns, furnaces, ovens, stoves, boilers, soaking pits, regenerators, mains and other combustion equipment. 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 prevent catastrophic failure of the refractory system. Often the hot face refractory can crack in service allowing the backup insulation to be exposed to elevated temperatures. ZIRCAL- 18 makes continued use of the operation possible, allowing for orderly shutdown and maintenance. In the aluminum industry, ZIRCAL-18 is ideally suited as an electrolytic cell insulation. Its combination of strength, thermal conductivity, stability and handleability makes it ideal for reduction cell applications. In the petrochemical industry, ZIRCAL-18 is ideally suited as a backup insulation in heaters and furnaces, and in applications requiring high strength such as insulated pipe. ZIRCAL-45 Type ZIRCAL-45 Refractory Board is a self-supporting, high strength, rigid refractory product fabricated from calcium silicate, inert fillers and reinforcing agents. Its high structural strength combined with high thermal insulating value make it ideal for many fireproofing and heat processing equipment applications up to 650°C(1202⁰F). ZIRCAL-45 is highly damage resistant, non-corroding, and extremely water- resistant. ZIRCAL-45 in full size 4’ x 8’ panels offer major economic advantages in the construction of ovens, dryers, and other insulated housings for the retention and control of heat. ZIRCAL-45 can be readily fabricated into various sizes and shapes for heat baffles and all types of insulating parts. It is used in fire safety applications such as fire stops, fire walls, cable trays and fire doors, and provides an ideal, incombustible base for melamine veneers. ZIRCAL-45 panels have flame spread and smoke developed ratings of 0 & 0, and are not damaged by inflammable charges that are subject to occasional flaming. ZIRCAL-45 is not affected by moisture or high humidity, and will not rust or corrode. The panels will not disintegrate even after prolonged immersion in water. While panels can be painted if desired, preservative treatments are not required for interior applications. ZIRCAL-45 is hygroscopic and electrical resistance is reduced when it absorbs moisture. For electrical applications, ZIRCAL-45 components should be thoroughly dried or moisture proofed before use. ZIRCAR Refractory Composites, Inc. P.O.
