Material Notes:
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(1202oF). ZIRCAL-45 is highly damage resistant, non-corroding, and extremely water-resistant.Information provided by ZIRCAR Refractory Composites, Inc. (ZRCI)
