General Info

 ZRCI Alumina-Silica Blanket Types RSBL-2300 and RSBL-2600 are mechanically-needled ceramic-fiber blankets that provide effective solutions to a variety of thermal management problems. RSBL-2300 and RSBL-2600 blankets exhibits good strength and handleability. They are low density with good chemical stability. RSBL-2300 and RSBL-2600 provide low thermal conductivity in numerous high-temperature laboratory and aggressive industrial environments. They have low shot content and are easily cut with scissors or knife. They are available in a wide range of density and thickness combinations.

They are available in two temperature ratings:

RSBL-2300 is made from spun Al2O3 -SiO2 refractory ceramic fibers (RCF) and is capable of long service life in applications with temperatures to 1260⁰C (2300⁰F).

RSBL-2600 is made from spun Al2O3 -SiO2 -ZrO2 refractory ceramic fibers (RCF) and exhibits extended service life in applications with temperatures to 1427⁰C (2600⁰F).

Types RSBL-2300 & RSBL-2600 Alumina Silica Blankets are ideal for use as furnace insulation in sintering, heat treating and chemical thermal process systems.
