Zircar Refractory Composites
The RSLE family of silica refractory composites are thermal shock resistant, not brittle and fully machinable to tight tolerances. Type RSLE-57 boards, RSLE-56 moldable and RSLE-501 cylinders are low expansion, high-strength reinforced silica-matrix composite products designed for use in applications that require a material having increased hot strength at temperatures to 2190F (1200C). The materials have good nonwettable properties when used in contact with molten aluminum, zinc, lead, tin and other nonferrous materials, making it useful in many metal-casting, conveying, containing and forming applications. They are 100% organic-free and contain no refractory ceramic fibers (RCFs).
