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 1100°C(2012°F). They also exhibit low thermal conductivities that remain relatively constant over a broad range of operating temperatures. 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.
