Vermiculite boards made from expanded vermiculite and special inorganic binder that provide a high degree of heat resistance to temperatures up to 1100 degree C and heat shocks. The boards do not represent any health hazards and are exclusive of any asbestos, glass or mineral fibers. They are resistant to CO and CH4 in the atmosphere, and to liquid aluminum, crylolites and fluorides. They feature sufficient rigidity and mechanical stability, high temperature and high electrical resistance and low heat conductivity. They are more than an adequate substitute for fireclay.
Max. service temperature: Up to 1100°C
