ZIRCAR Refractory Sheet Type RSLE-57 is a low expansion high strength reinforced silica matrix composite . This remarkable material was designed for use as a high strength insulator in induction hot press applications. RSLE-57's very low thermal expansion coefficient and high hot strength combine to give it thermal shock resistance not found in other structural ceramic matrix composite materials. RSLE-57's exhibits a very low coefficient of expansion 0.3 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 and becomes brittle. If the exceeded temperature is only localized, the material still retains its original high strength properties. RSLE-57 also exhibits exceptional non-wetting properties when used in contact with molten aluminum making it useful in numerous molten aluminum contact applications. RSLE-57 is 100% organic free and contains no refractory ceramic fiber. It is readily machined to precision tolerances with conventional tooling.
