Aluminum Silicate Ceramic Fiber Board: An Environmentally Friendly Insulation Material

Aluminum silicate ceramic fiber boards boast remarkable insulation properties making them a popular choice for high temperature insulation applications. They offer several advantages over traditional insulation materials:

Low Thermal Conductivity
Aluminum silicate ceramic fiber boards have an extremely low thermal conductivity ranging between 0.05 to 0.10 W/m•K, allowing them to insulate effectively at high temperatures up to 1200°C. By comparison, typical building insulation materials like expanded polystyrene have a thermal conductivity around 0.035-0.040 W/m•K. This makes alumina silicate board a superior choice for high temperature insulation applications.

Heat Resistance
Built using specially engineered ceramic fibers, aluminum silicate boards can withstand sustained operating temperatures up to 1200°C. They remain stable and perform consistently even after repeated exposure to such extreme heat. This heat resistance means they can help maintain the integrity of structures and equipment operating in high temperature environments.

Corrosion and Chemical Resistance
The inorganic nature of aluminum silicate ceramic fiber makes it highly chemically inert. It is resistant to most industrial acids, alkalis and salts, making it suitable for insulation in corrosive environments. The non- surface of the boards does not absorb liquids so they are widely used for piping, tanks and vessels containing various chemicals.

Alumina silica insulation ceramic fiber boards are zero flame rated, meaning they do not ignite, spread flames or produce significant heat when exposed to fire or high temperatures. They are therefore ideal for passive fire protection and can improve the fire rating of structures.

Lightweight and Flexible
Though effective at high temperatures, aluminium silicate ceramic fiber board is still lightweight and flexible, with densities typically below 100 kg/m3. They can be easily cut, formed and fitted into complex spaces while adding negligible load to any structure.

Eco-Friendly Insulation
Unlike some insulation materials which use harmful blowing agents to create low-density insulation, aluminum ceramic fiber boards are made from naturally occurring aluminosilicate minerals. They also contain no VOCs, formaldehyde or other toxic substances. The boards can be safely installed and handled with basic precautions and don’t require special disposal as hazardous waste after use.

Applications Of Aluminium Silicate Ceramic Fiber Boards

Some common uses of aluminium silicate ceramic fiber boards include:

Industrial Furnaces and Kilns – The high temperature insulation properties and heat resistance make them ideal for lining industrial furnaces, ovens and kilns operating at or above 1000°C. The boards help maintain an even heat distribution inside the heating chamber.

Exhaust System Insulation – Used to insulate exhaust ducts, manifolds and components of automotive, diesel and industrial engines where exhaust gas temperatures can exceed 800°C. They protect the ducts from heat while maintaining minimal thermal losses.

Piping and Vessel Insulation – Used to insulate industrial process pipes, tanks and vessels carrying or containing fluids at high temperatures. They can adhere directly to metal surfaces and withstand thermal cycling.

Chimney and Block Insulation – Used to provide insulation for chimneys, smoke stacks and industrial block insulation where there is continuous exposure to extreme heat and flame. The boards help reduce heat loss and cooling requirements.
