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. [1] [2] Fire retardants may also cool the fuel through physical action or endothermic chemical reactions.
Flame retardants manufactured for use in consumer products have been released into environments around the world. The flame retardant industry has developed a voluntary initiative to reduce emissions to the environment (VECAP) [87] by promoting best practices during the manufacturing process. Communities near electronics factories and disposal ...
Zinc borate is primarily used as a flame retardant in plastics and cellulose fibers, paper, rubbers and textiles.It is also used in paints, adhesives, and pigments.As a flame retardant, it can replace antimony(III) oxide as a synergist in both halogen-based and halogen-free systems. [3]
A DC-10 dumps fire retardant on Mandeville Canyon Road on Jan 11, 2025, during a battle to save the homes in the Brentwood community from the Palisades Fire that started on Jan. 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. Phos-Chek is produced in several colors, including red, uncolored, and fugitive. The colored retardant gradually fades to an earth-tone when exposed to sunlight. [9] The red color aids aircrews in targeting drops of ...
Hexabromocyclododecane (HBCD or HBCDD) is a brominated flame retardant. It consists of twelve carbon, eighteen hydrogen, and six bromine atoms tied to the ring. Its primary application is in extruded (XPS) and expanded (EPS) polystyrene foam used as thermal insulation in construction. Other uses are upholstered furniture, automobile interior ...
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.
One of the main applications of expandable graphite is as a flame retardant. When exposed to heat, expandable graphite expands and forms an intumescent layer on the material surface. This slows down the spread of fire and counteracts the most dangerous consequences of fire for humans, the formation of toxic gases and smoke. [4]
