ZIRCAR Refractory Composites, Inc. offers a wide range of insulating refractory papers. These non woven, non-asbestos, fiber-based products are engineered as thermal barrier materials for use in high temperature applications up to 1450°C (2642°F). Commonly used in the molten metal casting and heat treating industries, ZRCI materials are also used as specialty gasketing in the fuel cell, nuclear, glass and electronic industries, as well as many other applications which require high temperature stability and low thermal conductivity. They also offer excellent corrosion resistance and unique handling strength for easy die-cutting, wrapping and forming. ZRCI’s line of refractory paper include a binderless product for applications where outgassing cannot be tolerated, non-respirable grades where fiber content is of concern, and high purity compositions where the reducing of silica cannot be permitted. An additional type of refractory papers consists of soluble, Non RCF fibers formed into highly insulating sheets. The fibers are soluble in body fluids and offer an alternative to refractory ceramic fiber blankets. These grades of materials meet European regulatory requirements, (Directive 97/69/EC). Please refer to Refractory Sheet Type RSPA-SOL. Alumina-Silica Fiber Paper ZIRCAR Alumina-Silica Fiber Paper Type ASPA-1 and ASPA-2 are premium grade, lightweight refractory material made from high purity alumina-silica fibers formed into a highly flexible sheets. These alumina-silica fiber papers exhibit very low thermal conductivity and are designed for use in applications where purity, cracking resistance, high strength and resistance to heat are paramount.
