RS-100 Fiber Reinforced Structural Alumina Composite

Refractory Sheet Type RS-100 is a fiber reinforced structural Alumina composite with useful properties in thermal, structural and electrical insulation applications, as well as in the transport of molten non-ferrous metals to 1260OC(2300OF). Type RS-100 has compressive and flexural strengths in the range of high temperature reinforced plastics, such as G-10 laminates, but retains its strength and utility to levels far exceeding the maximum use temperatures of plastics. The mechanical properties of RS-100 exceed those of all calcium-silicate materials, as well as Transite and other asbestos cement materials, over all temperature ranges. Therefore, Type RS-100 not only makes an excellent replacement for rigid asbestos-containing products, but it can also be employed at much higher temperatures. Type RS-100 is 100% inorganic, non-flammable and contains no asbestos. Its high Alumina content makes it highly resistant to many environments, including molten non-ferrous metals, and it undergoes no out-gassing upon heating. It is not brittle and has high impact properties. RS-100 may be cut and machined with standard tooling.

RSLE-501 Cylinders

ZIRCAR Refractory Sheet Type RSLE-501 is a low expansion high strength reinforced silica matrix composites in a cylindrical form. This remarkable material was designed for use as a high strength, durable insulator in induction heat treating applications. RSLE-501’s very low thermal expansion coefficient and high hot strength combine to give it thermal shock resistance not found in other structural ceramic materials. 

RSLE- 501 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 will 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.

RSLE-501 also exhibits exceptional non-wetting properties when used in contact with molten aluminum making it useful in numerous molten aluminum contact applications.

RSLE-57 Silica Composites

ZIRCAR Refractory Sheet type RSLE-57 is a low thermal expansion, high strength reinforced silica matrix composite. Designed for use as a high strength insulator in induction hot press applications, it is ideal for any application which requires a material with superior hot strength at temperatures as high as 1200°C (2192°F). Beyond 1200°C (2192°F) it begins to transforms into a crystalline structure. RSLE-57 maintaining its properties up to 1650°C (3002°F) providing that there is no significant fall in temperature. At These elevated temperatures this the material will exhibit surface glazing while retaining its strength.

RSLE-57’s very low thermal expansion coefficient and high density combine to give it thermal shock resistance not found in other structural ceramic composite materials. These properties give it much greater life in most hot pressing and induction heating applications.

RSLE-57 exhibits exceptional non-wetting properties when used in contact with molten aluminum, zinc, lead, tin and other non-ferrous metals, making it useful in numerous casting, conveying, containing and forming applications. RSLE-57 is the ideal material for use as Dams, Spouts, Floats, Launders, Head Boxes, Baffles, Headers, Tips, Rings, Distribution Boxes, Stoppers, Basins, Snouts, Transition & Orifice Plates and Hot Top & Ingot Mold Liners. RSLE-57 is 100% organic free and contains no refractory ceramic fibers (RCF’s).
