  2. Fire retardant gel - Wikipedia

    en.wikipedia.org/wiki/Fire_retardant_gel

    When gel is applied to a surface such as an exterior wall, the water-filled bubblets can absorb much of the heat given off by the fire, thereby slowing the fire from reaching the wall. Gels can provide thermal protection from fire for extended periods even at 3,500 °F (1,930 °C).

  4. Firefighting foam - Wikipedia

    en.wikipedia.org/wiki/Firefighting_foam

    Firefighting foam is a foam used for fire suppression. Its role is to cool the fire and to coat the fuel, preventing its contact with oxygen, thus achieving suppression of the combustion. Firefighting foam was invented by the Moldovan engineer and chemist Aleksandr Loran in 1902. [1] The surfactants used must produce foam in concentrations of ...

    en.wikipedia.org/wiki/Flame_retardant

    A small study of US foam recyclers and carpet installers, who handle padding often made from recycled polyurethane foam, showed elevated levels of flame retardants in their tissues. [64] Workers in electronics recycling plants around the world also have elevated body levels of flame retardants relative to the general population.

    en.wikipedia.org/wiki/Polyurethane

    Polyurethane foam (including foam rubber) is sometimes made using small amounts of blowing agents to give less dense foam, better cushioning/energy absorption or thermal insulation. In the early 1990s, because of their impact on ozone depletion , the Montreal Protocol restricted the use of many chlorine -containing blowing agents, such as ...

    en.wikipedia.org/wiki/Building_insulation

    It is a kind of gel of which the liquid component of the material is replaced by a gas, thus creating a material that is 99% air. [41] This material has a relatively high R-value of around R-10 per inch which is considerably higher compared with conventional plastic foam insulation materials, due to their designed high porosity. [42]
