SG – (Structural Grade) Dense Refractory Products
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.
High Temperature Machinable Structural Ceramic Boards and Tubes
Structural Induction Furnace Lining
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°C (400°F) to 1649°C (3000°F).
Advantages: Structural and thermal shock resistant, machinable.
AirCER (AC) – Advanced Ceramic Fiber Products
AirCER (AC) are engineered ceramic fiber insulation materials often used as a superior alternative to conventional vacuum-formed ceramic fiber shapes and castable products.
AC Products are available in standard densities of 22 pcf, 30 pcf, and 45 pcf. Shapes reaching 60 pcf and 75 pcf densities are available upon request. These robust products are suitable for hot face temperatures of 2300°F to 3275°F. Product forms include boards, cylinders, and custom shapes.
Additional treatment options such as rigidizing and prefired shapes are also available.
Specialty Furnace Insulation Liner
Burner Block
Chemical Composition: Aluminosilicate to 99% Alumina.
Density: 0.35 g/cc (22 pcf), 0.48 g/cc (30 pcf), 0.71 g/cc (45 pcf), 0.95 g/cc (60 pcf), 1.19 g/cc (75 pcf).
Temperature Range: 1260°C (2300°F) to 1800°C (3275°F).
Advantages: Superior strength, erosion resistant, stable to very high temperatures and thermal cycling.
Shapes: Specializing in thick and large shapes for extremely harsh environments (i.e. areas of combustion). Quick turnaround of engineered shapes.
PF – Prefired Shapes
PF – Prefired Shapes offer exceptional chemical, thermal, and structural stability for a variety of industrial heating applications.
A wide variety of densities, ceramic compositions, and shapes to meet specific requirements is available upon request.
We can offer quick turnaround of special shapes by machining in-stock blocks of refractory. Additional options such as heat treat, additives, and surface coats are also available.
Specialty Refractory Shapes
Refractory Composition: Silica, alumina-based, magnesia-based, SiC, zirconia-based.
Density: 1.42 g/cc (90 pcf).
Temperature Range: 1204°C (2200°F) to 1649°C (3000°F).
Advantages: Thermal stability, wide selection.
