The new silica fiber blanket type SB-2000 is currently available from
ZIRCAR Refractory Composites, Inc. The new product 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 reportedly a strong needled
blanket with very good handling properties. According to the company,
the product is virtually shot free and has high resistance to attack
by most chemicals (exceptions include strong bases and hydrofluoric
acid). This blanket is not effected by thermal shock, exhibits
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. The composition of SB-2000 is 97.85% silica; the
silica fiber is 6-9 mm in diameter and has a melting point of 1698°C.
