ZIRCAR Refractory Sheet Type RS-D is a structural high-alumina product supplied in thin sheet form. It is composed of high purity alumina, reinforced with high-alumina ceramic fibers. Refractory Sheet Type RS-D is available in four types: two types of moldables, and two types of rigid sheets. TYPE RS-DA is a plastic highly moldable sheet ideally suited for forming custom geometries. TYPE RS-DM Sheet is a moldable form of Type RS-D with a higher density than obtainable from Refractory Sheet Type RS-DA. Type RS-DM is ideally suited for fabricating complex shapes from a flat sheet product for use in metal clad electric band and strip heaters. TYPES RS-DA & RS-DM can be readily cut with a knife or scissors. Joints can be made by wetting both surfaces with water (with a sponge or brush) and promptly pressing the two surfaces together. Thickness greater than 1/8" can be made by laminating two or more sheets together in this manner. Refractory Sheet Type RS-DD is suitable for die cutting or stamping of gaskets. It can be re-wet, made moldable, and handled like Type RS-DM. Type RS-DR cuts and handles similar to Type RS-DD except it is slightly less compressible and more rigid. It has been fired so that it will remain rigid even when wet. TYPE RS-DD is a rigid sheet that can be moistened with water to impart moldability. TYPE RS-DR is a rigid pre-fired sheet that has been heat-treated to remove all organic binder and is stable to moisture attack. Refractory Sheet Type RS-DR is suited for use as a setter or barrier for use in the sintering of powder metal parts (see Rigid Materials).
