Press Release Summary:
Refractory Sheet Type RSLE-57 exhibits low coefficient of expansion 0.3 x 10-6Â°C, which provides resistance to thermal shock up to 1,200Â°C in oxidizing atmosphere and permits use with rapid variation in temperature in that zone. Beyond 1,200Â°C, it transforms into crystalline structure, while maintaining properties up to 1,650Â°C. Corrosion-resistant RSLE-57 is 100% organic free and contains no refractory ceramic fiber.

Zircar Introduces New Refractory Sheet Type RSLE-57
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 w.
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, 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.
Other unique properties of RSLE-57 are:
o A low thermal conductivity.
o An excellent electrical insulation.
o A high chemical purity.
o An excellent resistance to corrosion (from molten metal and glass)
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.
