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 .
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]
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.
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, Perimeter Solutions.
Fire retardant [48] [49] [50] Anti-fungal compound for cellulose insulation [47] Mothproofing 10% solution for wool [51] Pulverized for the prevention of stubborn pests (e.g. German cockroaches) in closets, pipe and cable inlets, wall panelling gaps, and inaccessible locations where ordinary pesticides are undesirable [52]
Flame retardant coatings. [47] [48] [49] Flame-retardant materials and coatings are being developed that are phosphorus and bio-based. [50] These include coatings with intumescent functionality. [51] Non-stick PTFE coated cooking pots/pans. [52] Optical coatings are available that alter optical properties of a material or object. [53] UV ...
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 ...
The solution of orthoboric acid and borax in 4:5 ratio is used as a fire retarding agent of wood by impregnation. [38] It is also used in the manufacturing of ramming mass, a fine silica-containing powder used for producing induction furnace linings and ceramics. Boric acid is added to borax for use as welding flux by blacksmiths. [39]
