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.
