Benefits and properties
- High thermal conductivity
- Electrical conductivity
- Electromagnetic shielding
- Low powder density and large specific surface
- Minimum influence on properties of base material
- Environmental friendliness
Improvement of conductivity
A combination of gypsum plaster and SIGRATHERM GFG graphite powder improves the thermal conductivity of plasterboards by a factor of 3 to 0.52 W/(m•K), without impairing its basic properties.
Rigips Climafit plasterboards from Saint-Gobain Rigips GmbH provide an excellent, thermally efficient covering for surface heating/cooling systems.
Reducing electromagnetic exposure
With SIGRATHERM GFG graphite powder modified construction materials like Climafit Protekto plasterboards of Saint-Gobain Rigips GmbH are electrically conductive and therefore provide electromagnetic (EMI) shielding. The shielding is mainly achieved by absorption and not solely through reflection of the electromagnetic waves.
Application-specific suitability of our SIGRATHERM graphite powder
SIGRATHERM expanded graphite powders can be used in a wide variety of construction and HVAC applications where electrical and thermal conductivity properties are essential. Typical applications of our SIGRATHERM powders and granules are:
- Plasterboards for radiant ceiling installations
- Plasters for wall heating systems
- Antistatic floor coverings and adhesives
- Firebricks used for stoves
- Electrically or thermally conductive plastics
- Construction materials for electromagnetic shielding to protect e.g. hospitals, kindergartens, schools and living spaces
