Fire-retardant materials are designed to burn slowly.. Fire-retardant materials should not be confused with fire-resistant materials. A fire resistant material is one which is designed to resist burning and withstand heat.
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 ...
Foam glass or expanded glass is a porous glass foam material. It is used as a light weight, moisture- and fireproof building material with thermal and acoustic insulating properties. It is made by heating a mixture of crushed or granulated glass and a blowing agent (chemical foaming agent ), often carbon or carbonates such as limestone .

Spray foam insulation or spray polyurethane foam (SPF) is an alternative to traditional building insulation such as fiberglass. A two-component mixture composed of isocyanate and polyol resin comes together at the tip of a gun, and forms an expanding foam that is sprayed onto roof tiles, concrete slabs, into wall cavities, or through holes ...
Spray gypsum-based plaster fireproofing being installed. Circuit integrity fireproofing of cable trays, using calcium silicate boards. Damaged spray fireproofing. Fireproofing is rendering something (structures, materials, etc.) resistant to fire, or incombustible; or material for use in making anything fire-proof. [1]
By 1942 Fireproof Tanks had developed the first flexible fuel bladders as range extender tanks for the Spitfire Mk IX. These tanks were flexible containers, made of a laminated self-sealing material like vulcanized rubber and with as few seams as possible to minimize leak paths.
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.
