Zirconia Cloth and Felt provide the lowest thermal conductivity of any commercially available refractory material in their class. These flexible textile product forms are available in woven fabrics suitable for thermal insulation, high energy battery separators, filtration and protection applications under conditions of high temperatures and severe environments. The materials are true textiles in that they are constructed of essentially continuous individual filaments fabricated in standard textile forms. They require neither binders nor supporting wires in their construction and, therefore, are not limited in their application to the limitations of such auxiliary materials. This series of products offers a variety of thicknesses, cloth weaves and bulk densities.
All cloths are white in color.
Their flexibility is imparted by the fine diameter filaments and the multiple filament configuration that exists in a conventional textile. Each of the products described can be compressed up to two-thirds of its normal thickness and still recover a major fraction of its original dimension with little fiber damage. The inherently brittle nature of a ceramic material such as zirconia, while partially offset by the fibrous structure in these products, prevents these materials from withstanding shear forces such as might be encountered in tearing or grinding motions. Therefore, Zircar Zirconia Cloth materials perform best in applications where these motions are not encountered. These materials will tolerate exposure to a mineral acid at its boiling point for short lengths of time.
