General Info
ZRCI Refractory Sheet Type RS-200 is a fiber-reinforced ceramic laminate with useful properties to 1260°C (2300°F). This high temperature product offers high strength, moderate thermal conductivity and excellent electrical insulation. It retains its strength and utility to levels far exceeding maximum use temperatures of reinforced plastics and asbestos cement replacements. RS-200 is 100% inorganic, non-flammable and contains no asbestos. Its high alumina content makes it resistant to many environments including molten aluminum. RS-200 undergoes little or no outgassing on heating, is not brittle, and may be cut and machined with standard tooling. RS-200 is available in standard and custom boards and is useful as Specialty Furnace Components, Specialty High Temperature Electrical Thermal Insulation, Metal Working Components and Induction Furnace Components.
Compared to ZRCI Refractory Sheet Type RS-100 , RS-200 has the following attributes:
- Finer reinforcement structure which allows for machining of intricate detail
- Less tendency to delaminate
- Higher strength
Refractory Sheet Type RS-200 material is available in Cylinder form as Refractory Sheet Cylinders Type RS-201.

Composition
Refractory Sheet Type RS-100 Boards are ceramic fiber reinforced structural alumina composite material with useful properties to 1260°C (2300°F). They have flexural and compressive strength in the range of high temperature plastic but retain strength and utility to levels far exceeding maximum use temperatures of plastics. Mechanical properties of Type RS-100 sheets exceed those of asbestos cement materials over all temperature ranges. Their high Alumina content make them resistant to many environments including molten aluminum. They are not brittle and have high impact resistance. Type RS-100 is useful both as a full size panel and as a source for precision cut fabricated components. Type RS-200 Boards have all the properties of Type RS-100 with higher strength due to a finer reinforcement structure. This property makes Type RS-200 ideal for applications where intricate machining detail is needed. Types RS-101 and RS-201 & RS-202 Cylinders are fiber reinforced ceramic laminates in a cylindrical form. They exhibit the same properties as Type RS-100 and RS-200 respectively.
- Highest Compressive Strength
- High Alumina Content
- Chemical Resistant
- Fully Machinable to Tight Tolerances
- Non RCF
