Thermiculite® 870 is ahigh temperature sealingmaterial designed for
lowstresssealing in solid oxidefuelcells. It is based on the
mineralvermiculiteand contains no organic components.
Thermiculite® 870 is specifically designed for use in solid oxide fuel cells (SOFC) and solid oxide electrolysers (SOE) and has a high degree of compression combined with good sealing under low applied surface stresses.
Thermiculite® 870 contains only two minerals, vermiculite and steatite. There are no organic materials or other elements (such as phosphorous or sulphur) that would contaminate SOFC or SOE cell chemistry.
