ZIRCAR Refractory Composites, Inc. recently introduced its new ZIRCAL-18 refractory sheet board. The new board is a high-temperature calcium silicate block insulation with excellent mechanical properties and stability up to 1100C (2000F). 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, including firebrick, dense refractory brick, castable, gunning mix, plastic refractory or ceramic fiber. The product's high refractoriness and strength help prevent catastrophic failure of the refractory system.
