Refractory sheets. (Metalcasting Supplies).Zircar Refractory refractory Material that is not deformed or damaged by high temperatures, used to make crucibles, incinerators, insulation, and furnaces, particularly metallurgical furnaces. Composites, Inc. Zircar Refractory Composites, Inc., introduces refractory sheet cylinder type RS-201 and RS-202, fiber reinforced ceramic laminates with useful properties to 2300F (1260C). These high-temperature products offer high strength, moderate thermal conductivity thermal conductivity A measure of the ability of a material to transfer heat. Given two surfaces on either side of the material with a temperature difference between them, the thermal conductivity is the heat energy transferred per unit time and per unit and excellent electrical insulation Electrical insulation A nonconducting material that provides electric isolation of two parts at different voltages. To accomplish this, an insulator must meet two primary requirements: it must have an electrical resistivity and a dielectric strength . They retain their strength and utility to levels far exceeding maximum use temperatures of reinforced plastics and asbestos cement replacements. They are 100% inorganic, nonflammable non·flam·ma·ble adj. Not flammable, especially not readily ignited and not rapidly burned. and contain no asbestos.-- Select No. 005 at www.moderncasting.com/info. |
