PALUSOL® P&PM
Intumescent fire 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® P and PALUSOL® PM are intumescent fire seals made from PALUSOL®, a hydrated sodium silicate material, encapsulated in a rigid thermoplastic profile.
When exposed to fire, the PALUSOL is activated at a temperature of between 100 and 120°C, the 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 provides an effective barrier preventing the escape of any flames, smoke or hot gases around the perimeter of a fire-resistant element which is sealed in this way. In interior applications, the thermoplastic profile extends the service life of the PALUSOL P & PM intumescent seal by protecting it against humidity and from carbon dioxide, thus preventing weathering.
Profile colour: White, black, red, grey and brown. Other colours are also possible (please contact us).

Examples of applications for intumescent fire seals PALUSOL® P&PM: peripheral seals for fire resistant systems (doors, shutters, dampers, cabinets, walls, cable penetration systems etc.), enhancement of the fire resistance of various elements etc.
