ALUMINA-SILICA MOLDABLE BLANKETS Technical Data Bulletin No. ZRCI-032 Rev. March 2024 ZIRCAR Alumina-Silica Moldable Blankets Type RS-C Moldable are composed of long, high strength ceramic fibers, with an inorganic alumina binder/rigidizing agent. They are wet blankets that are shipped rolled up and sealed in a plastic bag to preserve their moldability. When dried, these moldable blankets form a strong, rigid, low density insulation. Type RS-C Moldable is ideal for applications to 1260°C (2300°F) and Type RS- CH for applications to 1450°C (2642°F). They are 100% inorganic, non-combustible and will not smoke upon initial heat up. They are ideal for insulation of complex shapes and can be cut to any size with a knife, scissors, or steel rule die. These moldable blankets possess excellent strength for ease of installation. A unique process of locking in the binder ensures that it will not migrate. The result is a uniform homogenous structure throughout the entire material. They exhibit excellent erosion resistance under conditions of high, hot gas velocity or molten non-ferrous metal flow. They can be further rigidized by using ZIRCAR Alumina Coat. However, Type RS-C and RS-CH Moldables do not adhere to themselves. They can be cemented using ZIRCAR's RS-Cemcoat They 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.
