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. An example of a fire-resistant material is one which is used in bunker gear worn by firefighters to protect them from the flames of a burning building.
Research on fire-retardant polymers was bolstered by the need for new types of synthetic polymers in World War II. The combination of a halogenated paraffin and antimony oxide was found to be successful as a fire retardant for canvas tenting. Synthesis of polymers, such as polyesters, with fire retardant monomers were also developed around this ...
Advocates for the flame retardant industry, such as the American Chemistry Council's North American Flame Retardant Alliance, cite a study from the National Bureau of Standards indicating that a room filled with flame-retarded products (a polyurethane foam-padded chair and several other objects, including cabinetry and electronics) offered a 15 ...
What is the fire retardant made of? The vibrant red fire retardant is known as Phos-Chek and has been used by firefighters battling wildland blazes for over 50 years, according to its manufacturer ...
A fire retardant is a substance that is used to slow down or stop the spread of fire or reduce its intensity. This is commonly accomplished by chemical reactions that reduce the flammability of fuels or delay their combustion .
From lowest (Least flame-retardant) to highest (Most flame-retardant): HB: slow burning on a horizontal specimen; burning rate < 76 mm/min for thickness < 3 mm or burning stops before 100 mm; V-2: burning stops within 30 seconds on a vertical specimen; drips of flaming particles are allowed.
The retardant is applied ahead of wildfires to homes [5] [6] and vegetation by ground crews and aerial firefighting units, either fixed-wing or rotary-wing aircraft. [7] As of 2022, Phos-Chek LC-95A is the most used fire retardant in the world. [8] A Phos-Chek tank trailer at Ramona Airport
Before the 1970s, PBBs were widely used commercially as a flame retardant. Michigan Chemical Corporation (MCC) in St. Louis, Michigan, which was then owned by Velsicol Chemical Corporation, was a major producer of the FireMaster range of PBB-based flame retardants. FireMaster BP-6 (a yellow-brown powder) is a mixture of many different PBB ...
