Product Description

Product Description

This products is an intumescent fire seal made from a hydrated sodium silicate material, encapsulated in a vinyl film 
When exposed to fire, which are activated at a temperature of between 212°F and 248°F (100°C and 120°C), the vinyl  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 218 PSI (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.
