An 
intumescent is a substance that swells as a result of heat  exposure, thus increasing in volume , and decreasing in density .
Kaynak: IntumescentBecause of the relatively low thickness of this 
intumescent coating (usually in the 350- to 700- micrometer  range), nice finish, and
Kaynak: Passive fire protectionThere are tests on system s, such as the one below, but there are also tests on materials, such as 
intumescent s, to be sure of components
Kaynak: Fire testIntumescent foam rubber firestops utilize Bayer  Fomox 
intumescent foam, which can be extruded into various shapes.  reinforced with
Kaynak: Firestop pillow Substitution of 
intumescent  and/or endothermic  fireproofing coatings with less expensive paints that physically resemble the passive fire
Kaynak: FireproofingFirestop components include 
intumescent s, cementitious mortars , silicone , firestop pillow s, mineral fibers , and rubber  compounds.
Kaynak: FirestopWhen 
intumescent seals are used in the door design, use of the correct seal is crucial in the fire rating performance the door assembly.
Kaynak: Fire doorPassive fire protection (PFP): Sodium silicates are inherently 
intumescent .  They come in prill (solid beads) form, as well as the liquid,
Kaynak: Sodium silicatePutties can also be made 
intumescent , in which case they are used for firestop ping as well as for padding of electrical outlet boxes  in
Kaynak: PuttyCommon fireproofing methods for structural steel include 
intumescent , endothermic and plaster coatings as well as drywall, calcium
Kaynak: Structural steelOther functions include 
intumescent  coatings for fire resistance.  The most common polymers used in industrial coatings are polyurethane
Kaynak: Industrial coatingAfter being lit, both fireworks begin to smoke and create ash resembling a snake via an 
intumescent  reaction.  They stay on the ground and
Kaynak: Black snake (firework)Uses : It is also used in some 
intumescent  systems. Zinc borate has synergistic effect with zinc phosphate  or barium borate  as a corrosion
Kaynak: Zinc borateThe resultant carbonaceous char is less-flammable than before Use as an 
intumescent  is achieved when combined with starch-based materials
Kaynak: Ammonium polyphosphateThe use of 
intumescent  "windows", which shut in case of a fire, can reduce or negate the effect of ampacity derating, subject to listing
Kaynak: Circuit integrityExterior fireproofing plasters are losing ground to more costly 
intumescent  and endothermic  products, simply on technical merit.

intumescent  coatings) at the finishing stage.
