Thermal properties and material types
Refractory bricks for thermal insulation and protection
Refractory insulating bricks are used within thermal processes and industrial installations where thermal insulation, heat resistance and installation protection are important.
Within the range, different types of refractory bricks are available for a wide range of temperature and process conditions.
Insulating bricks for high temperatures
Refractory insulating bricks combine a high insulation value with low heat storage and good mechanical properties.
Depending on the material and version, the materials are resistant to temperatures up to approximately 1800 °C.
In addition, the bricks offer good resistance to gas permeability.
Dense refractory bricks for heavy-duty applications
Dense refractory bricks are used within installations exposed to extreme mechanical, chemical or thermal loads.
The materials are used within, among others, the (petro)chemical industry and other applications involving high mechanical loads or corrosive conditions.
Dense bricks consist of materials including chamotte, high alumina and silica.
Versions, customisation and processing
Available in different materials and versions
Within the range, different materials are available, including:
- Moler (up to approximately 800 °C)
- Perlite (up to approximately 800 °C)
- Vermiculite (up to approximately 1100 °C)
In addition, refractory insulating bricks are available for temperature ranges from approximately 1260 °C to 1760 °C.
Special shapes and customisation possible
Refractory bricks are available in standard sizes and can also be custom machined.
Special shapes and combined versions are also possible depending on the application and installation conditions.
Mortars for installation and bonding of refractory bricks
Profiltra supplies Blakite mortar for bonding refractory bricks.
The mortar is resistant to temperatures up to 1760 °C and is available in 20 kg tins.
