GENERAL DESCRIPTION OF FLAME RETARDANT AGENT

Flame Retardant are substances that can be chemically inserted into the polymer molecule or be phisically blended in polymers after polymerization to suppress, reduce, delay or modify the propagation of a flame through a plastic materials. There are several classes of flame retardants Halogenated Hydrocarbons (Chlorine and Bromine containing compounds and reactive flame retardants), Inorganic flame retardants ( Boron compounds, Antimony oxides, Aluminium Hydroxide, molybdenum compounds, zinc and magnesium oxides ), Phosphorous containing compounds (Organic phosphate esters, phosphates, halogenated phosphorus compounds and inorganic phosphorus containing salts).
