Thermiculite® 866 - 866LS

Thermiculite® 866 & 866 LS are gasket materials capable of sealing in extremely high temperatures, specifically designed as a compression seal for Solid Oxide Fuel Cells (SOFC). Stable to temperatures up to 1000°C, Thermiculite® 866 & 866LS can also be used in other high temperature applications. The 866LS (Low-Stress) has an extremely thin layer of molten glass on each surface which seals the interfacial leakage paths under low load conditions and through thermal cycling events.
