General Info

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. They are as follows: 

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. (see Rigid Materials)

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).

Composition

Refractory Sheet Type RS-DA and RS-DM are structural high purity alumina forms reinforced with high alumina fibers. Type RS-DA is a plastic highly moldable sheet ideally suited for forming custom geometries. Type RS-DM is highly moldable with a higher density than Type RS-DA and is ideally suited for fabricating complex shapes from a flat sheet, for use in metal clad electric band heaters and strip heaters.

Refractory Sheet Type RS-DD and RS-DR are structural high purity alumina forms reinforced with high alumina fibers. Type RS-DD is a rigid sheet that can be moistened with water to impart moldability. Type RS-DR is a rigid prefired sheet which has been heat treated to remove all organic binder and is stable to moisture attack. Type RS-DR is ideal for use as a setter or barrier in the sintering of powder metal parts. Type RS-DD is widely used by Hot Glass Artist as slumping and fusing molds due to its non sticking nature.
