General Info
ZIRCAR Alumina-Silica Insulating Blanket Type RS-B 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-B Moldable forms a strong, rigid, low density insulation for applications to 900°C (1652°F). It is 100% inorganic, non-combustible and contains no toxic or hazardous materials. Type RS-B 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- B 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- B Moldable does not adhere to itself, yet it can be cemented using air-set mortar. Type RS- B 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- B Moldable can be put directly into high temperature ovens or furnaces.

Composition
Silica Moldable Type RS-SI Moldable is a wet blanket that is a combination of high purity amorphous silica fibers and inorganic silica binder. Upon drying Type RS-SI Moldable becomes a rigid structure with useful properties to temperatures of 1200°C(2192°F). It dries to a low mass light weight insulation with low thermal conductivity and high structural strength.
Alumina-Silica Moldable Blankets comprise long, high strength ceramic fibers in an inorganic Alumina binder/rigidizer. They are 100% inorganic and noncombustible. Alumina-Silica Blanket Type B is for applications to 900°C (1600°F) and Type C is for applications to 1260°C (2300°F). These materials harden to be a self supporting, extremely insulating ceramic fiber body.
- Immune to Thermal Shock
- Highly Insulating, Low Mass
- Strong Self Supporting When Dry
- Non RCF
