Moldable refractory sheet
max. 1 200 °C (2 192 °F) | RSLE-56
Zircar Refractory Composites
RSLE-56 exhibits a very low coefficient of expansion 1.0 x 10-6 °C which provides remarkable resistance to the thermal shock up to 1200°C (2192°F) in an oxidizing atmosphere and permits its use with rapid variation in temperature in that zone. Beyond 1200°C (2192°F) it transforms into a crystalline structure, while maintaining its properties up to 1650°C (3002°F) providing that there is no significant fall in temperature. At temperatures above this the material will exhibit surface glazing.
Engineered and produced with low thermal expansion raw materials RSLE-56 exhibits greater thermal shock resistance than moldable alumina matrix composites. RSLE-56's binder is locked in place and will not separate from its supporting fiber reinforcement resulting in an homogeneous structure throughout the material. RSLE-56 is 100% inorganic and once dried undergoes little or no outgassing.
RSLE-56 also exhibits exceptional non-wetting properties when used in contact with molten non-ferrous alloys making it useful in numerous molten metal contact applications.
RSLE-56 is 100% organic free and contains no refractory ceramic fiber. It is readily machined to precision tolerances with conventional tooling.
