ZIRCAR Alumina-Silica Insulating Blanket Type RS-C Moldable is composed of long, high strength ceramic fibers, with an inorganic alumina binder/rigidizing agent. It is a wet blanket that is shipped rolled up and sealed in a plastic bag to preserve its moldability.

Type RS-C Moldable forms a strong, rigid, low density insulation for applications to 1260°C (2300°F). It is 100% inorganic, non-combustible and contains no toxic or hazardous materials. Type RS-C Moldable is ideal for insulation of complex shapes and exhibits excellent erosion resistance under conditions of high, hot gas velocity. It can be cut to any size with a knife, scissors, or steel rule die. It can be formed to virtually any shape desired. Type RS-C Moldable possesses excellent strength for ease of installation. An unique process of locking in the binder ensures that it will not migrate. The result is a uniform homogeneous structure throughout the entire material.

Type RS-C Moldable does not adhere to itself, yet it can be cemented using air-set mortar. Type RS-C Moldable will normally air dry in 24 to 48 hours, with all the properties of a pre-fired insulation. Curing can be accomplished with a hot air gun or torch, or by immediate temperature exposure in the application.

Type RS-C Moldable can be put directly into high temperature ovens or furnaces.

Type RS-CH Moldable has all of the same properties as RS-C but is rated for 1450°C (2642°F)
