GENERAL INFORMATION
ZRCI Type RSMAT-3000 is
a high purity, high temperature, flexible
form composed of continuous 97% alumina ceramic fibers
designed for use to 1650°C
(3002°F). 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 low heat
capacity, and is immune to thermal shock. It is ideal for
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 to chemical 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 layersif 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. |
