Intumescent Gasket
Product Description
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.
