INTERDENS® 5, 15 & 36
Intumescent sheets & seals

Based on the three intumescent technologies (sodium silicate, ammonium phosphate and graphite), ODICE offers a wide range of fire seals and fire sheets. The co-extruded fire seals enhance a good cold smoke tightness and some extra dB for the acoustical insulation.

INTERDENS is an intumescent material made from ammonium phosphate which protects and enhances the fire resistance of wood and wood-based materials. It is available in semi-rigid boards and seals.

= balise ALTWhen exposed to fire, INTERDENS rapidly produces a large quantity of microporous, heat insulating foam, thereby protecting the treated material from fire. It hermetically fits into the gaps formed by distortion and prevents flames, smoke and gases from passing between two construction elements. 

Because of their size and sheet thickness, INTERDENS types 5 and 15 are suitable for protecting flat or curved surfaces by enhancing the fire resistance of construction elements.

In the form of cut strips, INTERDENS types 5 and 15 provide a means of creating a seal where gaps are reduced (partitions, the surrounds of inspection windows etc.).

When stamped, INTERDENS types 5 and 15 are used to protect the casings of latch locks and hinges, built-in metal fittings, thus limiting and mitigating combustion of the wood.

INTERDENS type 36 is used as fire resistant seals placed in grooves in structural components (ex: between the door leaf and the frame or wooden chassis).

Examples of applications for intumescent sheets & seals INTERDENS® 5, 15 & 36: partitions, the surrounds of inspection windows, the casings of latch, locks and hinges, built-in metal fittings etc.
