This versatile family of ceramic refractories, with its unique blend of structural, thermal, and electrical (non-conducting) properties, is ideal for virtually any high-temperature and structural insulation application.

A natural substitute for asbestos, plastic, wood, silicate, mica, metal, castable and vacuum-formed products, they’re available in a wide range of densities and chemical compositions.

Easy to machine, handle, and apply. Typical product forms include sheets, boards, cylinders, and engineered shapes.


Chemical Composition Range: Silica to aluminosilicate to alumina.

Density: 0.97 g/cc (60 pcf) to 2.30 g/cc (145 pcf).

Temperature Range: 232^oC (400^oF) to 1649^oC (3000^oF).

Advantages: Structural and thermal shock resistant, machinable.
