SILICA MOLDABLE  TYPE RS-SI 

(PDF VERSION)

GENERAL INFORMATION

ZIRCAR Silica Moldable Type RS-SI Moldable is a wet blanket that is a combination of high purity amorphous silica fibers and inorganic silica binder. The fibers are 6-9 um in diameter and are considered non-respirable. Upon drying, Type RS-SI Moldable becomes a rigid structure with useful properties to temperatures of 1100C (2012F).

Type RS-SI Moldable exhibits good wet handleability. It is easily cut with scissors or a knife and can be applied directly to equipment with complex contours. It can also be used to fabricate flat sheets or boards. Drying can be accomplished in an oven, with a hot air gun or torch, or by exposure to heat in the application. Drying results in a strong, rigid, low density shape that can be re-wet to restore the original moldability. Baking irreversibly removes the moldability, leaving Refractory Sheet Type RS-SI Moldable unaffected by moisture.

Type RS-SI Moldable exhibits excellent resistance to attack by most chemicals with the exception of caustics. It will tolerate all acids except hydrofluoric acid. It is not wet by molten aluminum . RS-SI Moldable is 100% organic free and contains no refractory ceramic fiber. It is readily machined to precision tolerances with conventional tooling.
