ZIRCAR Refractory Composites, Inc. Refractory Board Type ZIRCAL-18 SS60

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 supports.
