Material Notes:

Type ZIRCAL-95 Refractory Board is produced from a combination of natural organic fibers and inert reinforcing fillers in a high density calcium silicate hydrate matrix. Designed as a substitute for asbestos cement boards, ZIRCAL-95 is useful as structural and electrical insulation in applications with temperatures to 1100°C(2000°F). ZIRCAL-95`s surface is sanded smooth. It has a uniform consistency making it a useful source for custom machined insulating parts.Information provided by ZIRCAR Refractory Composites, Inc. (ZRCI)
