Fire intumescent seal ,fire intumescent seal ,intumesecnt material for door .
Intumescent fire seals products are those which expand (or intumesce) to several times their original size when activated by high temperatures. This action prevents the spread of flames and smoke to other parts of a building.
Under the action of heat, the PVC profile softens as the intumescent core expands sealing the gap between the door and the door frame, through which fire and toxic gas could pass. The amount of pressure developed by the expanding intumescent is dependent on the gap to be sealed. The wider the gap the lower the pressure.. The temperature at which Fireplug Intumescent strip starts to activate is 180 - 200 degrees centigrade. At this temperature no one would survive on the fireside of the door and in most cases the thermal shock would be fatal to anyone on the unexposed side opening the door. However, despite the requisite that the pressure developed by the expanding intumescent is sufficient to keep the door closed it is possible to make the door open if required.
The seals will start to expand at the temperature 260 celsius degree, and the main part expand temperature is 370 degree and it can expand 5 to 10 times.
Intumescent seals are a practical ,well established method of achieving fire resistance in desinate fire doors,Heat from a fire causes the intumescent material to foam and swell,thus filling the gap between the door and the frame and preventing the flow of hot gases and smoke. However, not all such seals are equal, and as concern over litigation grows, the thoughtful specifier must examine all the option to ensure that the seal chosen for each project really is the most appropriate. As the recognised leader in intumesent seal technology ,smallboss offers products of proven performance and demonstrable cost effectiveness whicn can be specified with absolute confiden.
