| 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).
Class of Flame Retardants
|
||
| OTHER INFORMATION | ||
|
Antimony trioxide and pentoxide don't react as flame retardants directly. They are used as synergists to enhance the activity of halogenated flame retardants by stepwise releasing the halogenated radicals to retard gas phase chain reaction of flame spread. | ||
