Plastics,textiles,surface finishes and coatings contains added chemical compounds as FLAME RETARDANTS that hinder,suppress, or bog down the production of flames to prevent the spread of fire.These are materials with large non-inflammable effect such as halogen, phosphorus, nitrogen containing compound, and hydroxide metallic compound, etc.Classified as Organohalogen compounds-organochlorines,organobromines,polymericbrominated;Organophosphoruscompounds,organophosphates,phosphonates,phosphinates,tris(2,3dibromopropyl)phosphate,chlorinated organophosphates.
APPLICATIONS-
- Electrical and electronics(wires and cables).
- Building and constructions(floors and walls).
- Automobile and transportation's(car bonnet and mudguard).
- Plastics and rubbers.
- Home appliances

-Thermal shielding : Spreading of flame over materials can be stopped by creating
a thermal insulation barrier between the burning and unburned parts.
Intumescent additives are often employed; their role is to turn the
polymer into a char, which separates the flame from the material and
slows the heat transfer to the unburned fuel.
-Dilution of gas phase : Inert gases produced by thermal degradation of some materials act as diluents of the combustible gases, lowering their partial pressures and the partial pressure of oxygen, and slowing the reaction rate.
-Gas phase radical quenching : Chlorinated and brominated materials undergo thermal degradation and release hydrogen chloride and hydrogen bromide or if used in the presence of a synergist like antimony trioxide antimony halides.
