PALUSOL® EF
Intumescent fire and cold smoke 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.


PALUSOL® EF is an intumescent fire seal made from PALUSOL®, a hydrated sodium silicate material, encapsulated in a rigid thermoplastic profile in combination with a protection against cold smoke.

In normal conditions of use, the PALUSOL® EF seal provides a seal against air and prevents the escape of what is known as cold smoke (below 150°C).

When exposed to fire, PALUSOL® is activated at a temperature of between 100 and 120°C, the seal profile runs and a rigid, non-combustible foam is formed which offers a high level of thermal insulation. In contact with heat, the intumescent material expands in one direction to at least five times its initial thickness. The expansion pressure thereby generated can reach 1,5N/mm2.This ensures continuity of sealing, thus providing an effective barrier preventing the escape of any flames, smoke or hot gases around the perimeter of the fire-resistant element sealed in this way. 

The range of  Intumescent fire and cold smoke seals PALUSOL® EF : Palusol EF DL, Palusol EF SDL, Palusol EF MAG2, Palusol EF V, Palusol EF BR.
