Exterdens^®

Exterdens^® foams with an inflation pressure of up to 10 bar at 150°C or 200°C and forms a microporous heat-insulating foam in the event of fire.

With the aid of graphite technology and the resulting inflation pressure, Exterdens^® can also be used in a concealed manner, for example under veneer, and also in areas exposed to moisture. In the event of fire, the foam expands three-dimensionally and achieves foaming factors of up to 25 of its original volume, thus insulating and sealing joints and cavities against the flashover of fire and smoke.

• Effective extension of the fire resistance of building components
• Can be used in areas exposed to moisture
• Low response temperature from as low as 150°C
• Excellent protection due to the heat-insulating properties of the compact foam
• The three-dimensional foaming and the high foam factor enable the filling of large joints and cavities
• Due to the low panel thickness, expensive (door) materials or complex (door) constructions are not required

Exterdens^® application range

Exterdens^® is designed for use in exterior areas and in areas with increased exposure to moisture.

Exterdens^® is used almost in all outdoor areas where passive fire protection is required. Exterdens^® is used, among other things, in:

• Fire doors and gates
• Windows/ glazing
• Partition walls, ceilings and floors
• Safety cabinets and safes
• Ventilation systems
• Elevator systems
• Pipe and cable penetration seals
• Installation shafts and cable ducts
• Curtain walls
• Wooden constructions
• and much more
