General Info
ZIRCAR Silica Blanket Type SB-2000 is a high temperature insulation blanket made of mechanically interlocked continuous filament amorphous silica fibers with useful properties to temperatures of 1100°C (2012°F).
SB-2000 is a strong needled blanket with very good handling properties. It is virtually shot free and has high resistance to attack by most chemicals. Exceptions include strong bases and hydrofluoric acid. This blanket exhibits thermal shock immunity, thermal conductivity and heat storage in the range of refractory ceramic fiber (RCF) blanket and is useful in many applications where RCF is not desired.
