Fitherm® IG is a newly developed graphite based intumescent gasket. Designed and extruded in different forms, Fitherm® IG can seal the corresponding joint against air transfer and humidity under normal conditions.
In case of fire Fitherm® IG expands to multiple times its original volume, forms a heat-isolating shield and stops the spreading of fire and hot gases. Fitherm® IG starts expanding at around 200°C.
|approx. 1.35 g/cm³
|starting from 200°C
|up to 9-fold its original thickness
|start approx. 1.4 N/mm²
Fitherm IG is developed for a wide range of applications where an intumescent material is necessary to maintain the system integrity and insulation in case of fire. These systems are for example:
- fire doors and glazing systems
- fire safes
- special containers
Fitherm® IG can be customised to special forms for multiple applications.
