Advantages of Flame Retardant

-
Prevents fire/retards its growth and spread (flash over)
Under the conditions of fire, the use of flame retardant gives a significant increase in the escape time available. It controls the fire properties of combustible items.
-
Protects occupants from the fire effects
The use of fire retardant reduces the flame spread and thus, the rate at which the smoke develops. Less smoke production gives an increase in the escape time available.
-
Minimizes the impact of fire
It provides separation by tenant, occupancy, or maximum area. It maintains the structural integrity of the property. It provides continued operation of shared properties.
-
Supports fire service operations
To prevent the fire or retard its growth and spread, material and product performance testing is used. It sets limits on the fire properties of items that represent the major fuels in the system.

Features of Flame Retardant
White powder, no poison, no smell and noncorrosion. IndissoIvable in water, ethyl alcohol, acetone, benzene etc.
The product has properties of high bromine content, excellent thermal stability, low toxicity and UV-resistance. It is used in high-impact polystyrene(HIPS), engineering plastics, wires and cables, insulator, elastomer and thermoset plastics etc.
Types of Flame Retardant
Reactive flame retardants
Incorporated into the polymer or material through a chemical reaction, becoming a permanent part of the material itself.
Additive flame retardants
Physically mixed into and encased by the material they are designed to protect.
Application of Flame Retardant
Electronics and electrical devices: Electronics are a marvel of modern technology. We’ve learned to harness the power of electricity, and used it to do some pretty crazy things. However, these products can get overloaded and wires can get crossed, and sometimes they start fires.
Building and construction materials: Construction materials have come a long way, and some of the most important advancements relate to safety. A hundred years ago, a house fire may have meant that the entire block or city went up in flames.
Home and office furnishings: Anything that is comfortable is typically flammable. From the wood frame, to the filling, to the upholstery, furniture is a tinderbox that speeds fires through homes. The flame retardant materials used in modern furniture give people much needed time to escape should a fire start indoors.
Transportation: Most modern transportation still relies on internal combustion, so heat and fire come with the territory. They are also fitted with highly combustible fuel tanks. In the event that fire spreads through the conveyance, the flame retardants used in its construction may save your life.
