Interdens®

Interdens® foams without pressure at a very early stage at 150°C and forms a microporous heat-insulating foam in the event of fire.

Due to the phosphate-based technology, a two-phase foaming process begins at 150°C and is followed by a further surge at 300°C. This results in very high foaming factors of up to 95 times its original volume. Without pressure, the foam spreads three-dimensionally into joints and crevices and prevents fire and smoke from spreading into other rooms.

Advantages of Interdens®

Intumescing Action

Two-phase and three-dimensional intumescing action at 150°C and 300°C

Intumsescence Factor

Fine-pored foam with reliable intumescence of up to 95 times the original thickness

Cost Savings

Low board thickness of 0.6 – 2.0 mm enables the use of modern hardware

 

  • Thermal insulation properties of the fine-pored foam provide excellent protection against increased heat input
  • Low response temperature and two-phase foaming process
  • Three-dimensional foaming and very high foaming factor allow filling of large joints and cavities
  • Effective extension of the fire resistance duration of building components
  • Due to the very low panel thickness, expensive (door) materials or complex (door) constructions are not required

Area of application Interdens®

Interdens®is designed for use in interior areas and areas not exposed to moisture.

Interdens® is used in almost all interior areas where passive fire protection is required, such as door locks, hinges or metal fittings.

Cut strips or stamped parts equipped with a self-adhesive finish can be used to fill narrow joints and reliably seal them in the event of fire. It is also possible to protect surface of building components using cut sheets.

Interdens® is used, among other things, for:

  • Fire doors and gates
  • Windows / glazing
  • Facades
  • Wooden constructions
  • and many more

Interdens® product range

The Interdens® product range includes factory-made sheet and roll products, some of which are available with self-adhesive finish. Processed further as a die-cut or strip product, it protects against smoke and flame flashover, particularly in the area of metal door fittings, glazing and building component edges.
