Type RSMAT-3000 contains little shot and has a higher alumina content than any other ceramic fiber mat or blanket. Type RSMAT-3000 is lightweight, has low thermal conductivity and lowheat capacity, and is immune to thermal shock. It is idealfor vacuum, reducing atmospheres and other applications where silica cannot be tolerated, such as powder metal sintering, stainless steel bright annealing and many fuel cell applications.

Type RSMAT-3000 demonstrates excellent resistance tochemical attack and is not affected by oil or water. It's thermal and physical properties are restored after drying. It is, however, affected by hydrofluoric acid, phosphoric acid and strong alkalis. Type RSMAT-3000 contains no organic binders and will produce no smoke or odors when heated. It's non-needled layered construction allows the user to easily peel apart the mat to achieve thinner layers if desired.

The Fibers used in RSMAT-3000 were designed with the expert advice of toxicologists to minimize the potential for biological activity. They are produced in a spinning process from a viscous aqueous solution to give a narrow diameter distribution. They are all then subjected to a controlled heat treatment to develop a polycrystalline microstructure. An extensive series of toxicological tests were carried out on the fiber, involving inhalation, injection and feeding studies. All results were negative, with no fibrogenic, carcinogenic or other toxic effects found. Low silica levels ensure that there is no possibility of Cristobalite formation after exposure to high temperature. Type RSMAT-3000 fibers are not subject to European regulatory constraints and do not require a hazard warning label or special handling procedures for installation or disposal after use.
