ZRCI Refractory Sheet Type RS-101 is a ceramic fiber reinforced structural alumina product with useful properties to
2300°F (1260°C). It retains strength and utility to levels far exceeding maximum use temperatures of reinforced plastics and asbestos-cement replacements. Type RS-101 not only makes an excellent replacement for rigid asbestos containing products, but also may be employed at much higher temperatures as well. Type RS-101 is 100% inorganic, non-flammable and contains no asbestos. Its high
Al2O3 content makes it resistant to many environments including no outgassing on heating, is not brittle, and may be cut and machined with standard tooling. Type
RS-101 is available in standard and custom size cylinders.
Refractory Sheet Material is available in board form as Refractory Sheet Type
RS-100

TOLERANCE
±1/16" inside diameter, wall thickness and length.
SURFACE FINISH:
Standard cylinders have textured inside and outside surfaces (which mimics the structure of the reinforcing fabric). Ends are saw cut. Burnished surfaces are available on a custom basis.
CUSTOM CYLINDERS:
Our forming process allows a wide range of cylinders to be made from inside diameter of 3/4" with lengths to 72" to inside diameter of 36" with lengths to 36" and wall
thickness of 1/16" to 1".
Tolerance schedules can vary with cylinder size. We can also supply custom geometries such as round corner square cylinders, troughs, oval cylinders, channel, angle, etc. Contact ZIRCAR with your specific requirements.
