ZIRCAR Ceramics’ Alumina-Silica Insulation Type ECO-1200 is a useful utility grade of refractory ceramic fiber (RCF) insulation board suitable for use to 1260°C (2300°F). ECO-1200 has good strength and machinability with relatively smooth surfaces. It is manufactured in two grades.
ECO-1200A: In addition to its inorganic amorphous (colloidal) silica binder ECO-1200A contains a few percent organic binder which aids in room temperature handleability and machinability.
ECO-1200B: has had its organic binder burned out and is organic-free.
Both grades offer low thermal conductivity, excellent thermal shock resistance and are an effective thermal insulator in numerous thermal process systems. ECO-1200 exhibits excellent resistance to chemical attack and is not affected by oil or water. It is, however, affected by hydrofluoric acid, phosphoric acid and strong alkalis.
