FibroCeram Materials
FibroCeram Materials
Ceramic fiber tubes are engineered from a blend of refractory fibers (primarily aluminum silicate rubber cotton felt) combined with inorganic binders and trace organic additives. Through advanced processes including high-temperature melting, fiber formation, mold processing, and curing, these tubes achieve exceptional thermal stability with service temperatures ranging from 1000°C to 1800°C.
