Low Pressure Intumescent Resin: This product is suitable for use in passive fire protection in general, firestopping and fireproofing in particular. The small, orange chunk on the bottom right hand side is capable of growing into that large black shape. This type of intumescent is typically highly endothermic. It contains a lot of chemically bound water, in hydrates. As this is released, it cools adjacent materials. Such intumescents are useful as ingredients in firestop pillows and in paints, which are used for fireproofing purposes. These intumescents do not produce enough expansion force to be used in plastic pipe devices, where the intumescent must squeeze a melting plastic pipe or conduit shut.

Pipes covered with a thin-film intumescent spray fireproofing product called unitherm. As the flame from the blow-torch hits it, the intumescent expands, forming a layer of insulation, which slows down heat transfer to the pipe below. Hydrates within the coating give up their water content, maintaining a temperature near the boiling point of 100°C. The critical steel temperature is ca. 540°C. Once the water is spent and enough heat has gone through the char, the steel can reach and exceed its critical temperature and then lose its strength. The time this takes determines the fire-resistance rating. Image File history File links Unitherm1. ... Pipe is a tube or hollow cylinder for the conveyance of fluid. ...

In this picture, the flame has been removed after the thin-film intumescent spray fireproofing product has been completely expanded. Some intumescents can undergo shrinkage shortly after full expansion has taken place. The important thing to remember, however, is the need for bounding of the installed configuration.

Intumescent putty, permanently pliable, used in a cable penetration firestop. Permanently pliable putties are similar in consistency to play-dough used for children's toys. Putties of this nature also lend themselves to be used as pads to cover electrical outlet boxes inside drywall assemblies required to have a fire-resistance rating. The endothermic and insulative action of the pads reduce thermal transfer through the metallic outlet box to the unexposed side of the rated drywall assembly. All intumescents must be installed in a manner consistent with bounding requirements. Image File history File links No higher resolution available. ...

A passive fire protection example of an intumescent with strong expansion pressure. This intumescent is called Palusol. It is based on waterproofed sodium silicate. Another high-expansion intumescent popular for use in plastic pipe firestop devices is graphite. Graphite tends to be less affected by atmospheric conditions than many water-bearing intumescents.

Construction of a test sample, consisting of a mock-up concrete floor frame, complete with penetrants. The concrete frame measures approximately 5’ x 9’ x 4" (ca. 1.5m x 2.3m x 10cm). It has a large hole in the centre with many mechanical and electrical services traversing. The penetrants extend 1’ (30cm) into the furnace and 3’ (91cm) on the unexposed side. A firestop mortar is being applied here. Notice the intumescent wrap strip surrounding the fibreglass pipe insulation. When the fire starts, this embedded intumescent will swell to take up the place of the melting insulation. The test was conducted in accordance with the Canadian firestop test method ULC in Scarborough, Ontario.^[3] Image File history File links No higher resolution available. ...
