RS-A is a tough ceramic fiber reinforced composite material available in standard boards and custom shapes made to customer specifications.

These products are made from Type RS-A Moldable. Type RS-A was developed as an asbestos board replacement for induction coil liners and molten metal transport, and contains no asbestos. Refractory Sheet Type RS-A is ideally suited for a wide range of high temperature, high thermal shock applications.

Type RS-A contains no organic binders and will produce no smoke or odors when heated.

Type RS-A products are available in 3 varieties: Type RS-A1 is dried to constant weight at 100°C(212°F). These products can be remoistened to impart moldablity. Type RS-A2 is fired for 3 hour at 600°C(1112°F) and fully cured. Type RS-A3 is fired, hardened with ZRCI AL-Hard at 5% pickup, and re fired. They are substantially higher in density than other ceramic fiber based moldable derived products.
